FIELD OF THE INVENTION

This application is directed to materials for golf ball layers and, inparticular, a polyurea-based material that is suited for golf ball coverlayers, more specifically outer cover layers.

SUMMARY OF THE INVENTION

The present invention is directed to a golf ball comprising a core, aninner cover layer, and an outer cover layer. The outer cover layer isformed from a polyurea material comprising a prepolymer and a curative.The prepolymer consists of an aliphatic isocyanate mixture comprisingdimerized uretdione of HDI and trimerized isocyanurate of HDI and afirst amount of modified polyoxypropylene diamine having a formula:

where x=1-70; R₁ and R₂ each independently=a C₁₋₂₀ alkyl group, phenyl,or a mixture thereof; and R₃=H, CH₃, or a mixture thereof. Nocaprolactone is present in the prepolymer. The curative is a mixture of3,5-diethyl-2,4-toluenediamine and 3,5-diethyl-2,6-toluenediamine.Optionally, the aliphatic isocyanate mixture further includes thetrimerized biuret of HDI. To assure that the polyurea does not containany substantive polyurethane linkages, the modified polyoxypropylenediamine ideally does not contain an —OH group. The isocyanate mixturetypically has 6% free isocyanate to 9.5% free isocyanate.

In one embodiment, the core is a dual core and includes a solid centerand an outer core layer. The center preferably has an outer diameter of0.095 inches to 1.1 inches. The core, whether single or dual core,typically has an Atti compression of 75 or less. The outer cover layerhas a material hardness of 70 Shore C to 80 Shore C and a hardness, asmeasured directly on the golf ball, of 40 Shore D to 55 Shore D, whichis not inherent and is more a function of layer thickness and thehardness of the underlying layer. In a preferred embodiment, the outercover layer has a first hardness and the inner cover layer has a secondhardness, and a ratio of the first to second hardness is 0.8 to 0.7.

In another embodiment, the outer cover layer has a thickness of 0.025inches to 0.04 inches. The inner cover layer generally has a thicknessof 0.01 inches to 0.045 inches, more preferably 0.025 inches to 0.035inches. In another embodiment, the core has an outer diameter of 1.5inches to 1.6 inches.

The present invention is also directed to a golf ball consisting of acore and an outer cover layer. The outer cover layer is formed from apolyurea material including a prepolymer and a curative. The prepolymerconsists of an aliphatic isocyanate mixture including a dimerizeduretdione of HDI and trimerized isocyanurate of HDI (or, optionally, atrimerized biuret of HDI) and a modified polyoxypropylene diamine. Thecurative includes a mixture of 3,5-diethyl-2,4-toluenediamine and3,5-diethyl-2,6-toluenediamine. No caprolactone is present in theprepolymer and to help ensure that no substantive urethane linkages arein the polyurea, the modified polyoxypropylene diamine preferably doesnot contain an —OH group.

In one embodiment, the core is a dual core and includes a solid centerand an outer core layer. In another embodiment, the golf ball furtherincludes an inner cover layer disposed between the outer core layer andthe outer cover layer, the inner cover layer having a thickness of 0.02inches to 0.04 inches. The golf ball preferably has an Atti compressionof 95 to 120. In an alternative embodiment, the golf ball furtherincludes an inner cover layer disposed between the core and the outercover layer, the inner cover layer and outer cover layer each having athickness of 0.01 inches to 0.045 inches.

DETAILED DESCRIPTION OF THE INVENTION

The present disclosure relates to golf equipment such as golf balls,golf clubs (drivers, putters, woods, irons, and wedges, including headsand shafts thereof), golf shoes, golf gloves, golf bags, or the likethat comprise novel polyurethane, polyurea, and/orpoly(urethane-co-urea) compositions. The components of the compositionscan be saturated, i.e., substantially free of double or triplecarbon-carbon bonds or aromatic groups, to produce light stablecompositions. Components that are unsaturated or partially saturated canalso be used.

The golf ball can comprise at least one thermoplastic, thermoset,castable, or millable material formed from a composition comprising atleast one poly(urethane-co-urea) prepolymer and at least one curative.The poly(urethane-co-urea) prepolymer can be formed at least in partfrom at least one aminoalcohol telechelic and at least onepolyisocyanate. The aminoalcohol telechelic can be linear, branched,block, graft, monodisperse, polydisperse, regular, irregular, tactic,isotactic, syndiotactic, stereoregular, atactic, stereoblock,single-strand, double-strand, star, comb, dendritic, and/or ionomeric.The aminoalcohol telechelic can be chosen from homopolymers, randomcopolymers, pseudo-copolymers, statistical copolymers, alternatingcopolymers, periodic copolymer, bipolymers, terpolymers, andquaterpolymers. The aminoalcohol telechelic can comprise at least onepolymeric structure chosen from polyhydrocarbons, polyethers,polyesters, polyamides, polycarbonates, polyacrylates, polysiloxanes,and copolymers thereof. The composition can further comprise at leastone reactant chosen from isocyanates and curatives, or at least oneisocyanate-containing prepolymer where the aminoalcohol telechelic isused to cure the prepolymer. The aminoalcohol telechelic can be areaction product of at least one polyamine telechelic and at least onecyclic compound chosen from cyclic esters and cyclic amides. Thepolyamine telechelic can have a molecular weight of 200-5,000, and canbe a polyether polyamine chosen from diamines and triamines ofpolyoxyethylene, polyoxypropylene, andpoly(oxyethylene-co-oxypropylene). The cyclic compound can be chosenfrom caprolactone, caprolactone diols, and caprolactone triols. Thepoly(urethane-co-urea) prepolymer can be an in situ polymerizationproduct of at least one polyamine telechelic, at least one cyclic esterand/or cyclic amide, and at least one polyisocyanate chosen fromuretdione dimers and isocyanurate trimers. The poly(urethane-co-urea)prepolymer can have a viscosity of 1,000-4,000 cP at temperatures ofabout 125° C. or less.

The material can at least in part form at least one portion of the golfball chosen from inner center, core, inner core layer, intermediate corelayer, outer core layer, intermediate layer, cover, inner cover layer,intermediate cover layer, outer cover layer, discontinuous layer, woundlayer, foamed layer, lattice network layer, web or net, adhesion orcoupling layer, barrier layer, layer of uniformed or non-uniformedthickness, layer having a plurality of discrete elements, and layerfilled with liquid, gel, powder, and/or gas. In one example, the golfball can comprise a core comprising at least a first portion, and acover comprising at least a second portion, wherein the material isdisposed in at least one of the first and second portions, and/orbetween the core and the cover. The material can at least in part format least one cover layer having a thickness of 0.125 inches or less anda Shore D hardness of 20-80.

Golf equipment can be formed from a variety of compositions. Balata, anatural or synthetic trans-polyisoprene rubber, has been used to formgolf ball covers. Olefinic ionomer resins have also been used as covermaterials. Chemically, olefinic ionomer resins are copolymers of olefin(such as ethylene) and α,β-ethylenically unsaturated carboxylic acid(such as acrylic acid or methacrylic acid) that have 10% to 100% of thecarboxylic acid groups neutralized by cations (such as metal cations).Examples of commercially available olefinic ionomer resins include, butare not limited to, SURLYN® from Du Pont de Nemours and Company, andESCOR® and IOTEK® from ExxonMobil.

Polyurethanes are useful materials for golf ball covers. Polyurethanecovers can be polyurethane prepolymers cured with curing agents havingat least one active hydrogen groups (such as amines and/or polyols),wherein the prepolymers are formed of hydroxy-terminated telechelicswith polyisocyanates. Polyureas formed of polyurea prepolymers andcuratives are relatively new choices for golf ball materials.Polyurethanes and polyureas can be thermoset or thermoplastic, dependingat least in part on the curing agent used. Unsaturated components (suchas aromatic diisocyanate, aromatic polyol, and/or aromatic polyamine)used in a polyurethane or polyurea composition are at least in partresponsible for the composition's susceptibility to discoloration anddegradation upon exposure to thermal and actinic radiation, such asultraviolet (UV) light. Substituting the unsaturated components withpartially unsaturated or saturated components can enhance lightstability of the composition. Highly light-stable compositions mayinclude only substantially saturated components. As used herein, theterm “saturated” or “substantially saturated” means that the compound ormaterial of interest is fully saturated (i.e., contains no double bonds,triple bonds, or aromatic ring structures), or that the extent ofunsaturation is negligible, e.g., as shown by a bromine number inaccordance with ASTM E234-98 of less than 10, such as less than 5. Thecompositions of the disclosure may also include at least one lightstabilizer to improve light stability, especially when unsaturated(e.g., aromatic) components are used.

Moisture absorption is another mechanism through which desirablephysical properties in the composition are compromised. This can beremedied, for example, by incorporating at least one moisture vaporbarrier layer in the golf ball. Alternatively, the use ofwater/moisture-resistant compositions in golf ball components leads to agolf ball with improved shelf-life and/or use-life. Conventionalpolyurethane and polyurea golf ball covers can be prone to absorption ofmoisture. Incorporation of hydrophobic backbones into the compositionscan reduce moisture absorption and water/moisture permeability, asreflected in reduced water vapor transmission rate (WVTR).

As used herein, the terms “araliphatic,” “aryl aliphatic,” or “aromaticaliphatic” all refer to compounds that contain one or more aromaticmoieties and one or more aliphatic moieties, where the reactablefunctional groups such as, without limitation, isocyanate groups, aminegroups, and hydroxyl groups are directly linked to the aliphaticmoieties and not directly bonded to the aromatic moieties. Illustrativeexamples of araliphatic compounds are o-, m-, and p-tetramethylxylenediisocyanate (TMXDI).

The subscript letters such as m, n, x, y, and z used herein within thegeneric structures are understood by one of ordinary skill in the art asthe degree of polymerization (i.e., the number of consecutivelyrepeating units). In the case of molecularly uniformed products, thesenumbers are commonly integers, if not zero. In the case of molecularlynon-uniformed products, these numbers are averaged numbers not limitedto integers, if not zero, and are understood to be the average degree ofpolymerization.

Any numeric references to amounts, unless otherwise specified, are “byweight.” The term “equivalent weight” is a calculated value based on therelative amounts of the various ingredients used in making the specifiedmaterial and is based on the solids of the specified material. Therelative amounts are those that result in the theoretical weight ingrams of the material, like a polymer, produced from the ingredients andgive a theoretical number of the particular functional group that ispresent in the resulting polymer.

As used herein, the term “polymer” is used to refer to oligomers,adducts, homopolymers, random copolymers, pseudo-copolymers, statisticalcopolymers, alternating copolymers, periodic copolymer, bipolymers,terpolymers, quaterpolymers, other forms of copolymers, substitutedderivatives thereof, and mixtures thereof. These polymers can be linear,branched, block, graft, monodisperse, polydisperse, regular, irregular,tactic, isotactic, syndiotactic, stereoregular, atactic, stereoblock,single-strand, double-strand, star, comb, dendritic, and/or ionomeric.

As used herein, the term “telechelic” is used to refer to polymershaving at least two terminal reactive end-groups and capable of enteringinto further polymerization through these reactive end-groups. Reactiveend-groups disclosed herein include, without limitation, amine groups,hydroxyl groups, isocyanate groups, carboxylic acid groups, thiolgroups, and combinations thereof.

Other than in the operating examples, or unless otherwise expresslyspecified, all of the numerical ranges, amounts, values and percentagessuch as those for amounts of materials, times and temperatures ofreaction, ratios of amounts, values for molecular weight (whether numberaverage molecular weight (“M_(n)”) or weight average molecular weight(“M_(w)”), and others in the following portion of the specification maybe read as if prefaced by the word “about” even though the term “about”may not expressly appear with the value, amount or range. Accordingly,unless indicated to the contrary, the numerical parameters set forth inthe following specification and attached claims are approximations thatmay vary depending upon the desired properties sought to be obtained bythe present disclosure. At the very least, and not as an attempt tolimit the application of the doctrine of equivalents to the scope of theclaims, each numerical parameter should at least be construed in lightof the number of reported significant digits and by applying ordinaryrounding techniques.

Notwithstanding that the numerical ranges and parameters setting forththe broad scope of the disclosure are approximations, the numericalvalues set forth in the specific examples are reported as precisely aspossible. Any numerical value, however, inherently contain certainerrors necessarily resulting from the standard deviation found in theirrespective testing measurements. Furthermore, when numerical ranges ofvarying scope are set forth herein, it is contemplated that anycombination of these values inclusive of the recited values may be used.

For molecular weights, whether M_(n) or M_(w), these quantities aredetermined by gel permeation chromatography using polystyrene asstandards as is well known to those skilled in the art and such as isdiscussed in U.S. Pat. No. 4,739,019 at column 4, lines 2-45, which isincorporated herein by reference in its entirety.

As used herein, the terms “formed from” and “formed of” denote open,e.g., “comprising,” claim language. As such, it is intended that acomposition “formed from” or “formed of” a list of recited components bea composition comprising at least these recited components, and canfurther comprise other non-recited components during formulation of thecomposition.

As used herein, the term “cure” as used in connection with acomposition, e.g., “a curable material,” “a cured composition,” shallmean that any crosslinkable components of the composition are at leastpartially crosslinked. In certain examples of the present disclosure,the crosslink density of the crosslinkable components, i.e., the degreeof crosslinking, can range from 5% to 100% of complete crosslinking. Inother examples, the crosslink density can range from 35% to 85% of fullcrosslinking. In other examples, the crosslink density can range from50% to 85% of full crosslinking. One skilled in the art will understandthat the presence and degree of crosslinking, i.e., the crosslinkdensity, can be determined by a variety of methods, such as dynamicmechanical thermal analysis (DMTA) in accordance with ASTM E1640-99.

The compositions of the present disclosure typically comprise a reactionproduct of a polyisocyanate and one or more reactants. In one example,the reaction product can be a polyurethane formed from a polyurethaneprepolymer and a curative, the polyurethane prepolymer being a reactionproduct of a polyol telechelic and an isocyanate. The polyol telecheliccomprises at least two terminal hydroxyl end-groups that areindependently primary, secondary, or tertiary. The polyol telechelic canfurther comprise additional hydroxyl groups that are independentlylocated at the termini, attached directly to the backbone as pendantgroups, and/or located within pendant moieties attached to the backbone.The polyol telechelic can be α,ω-hydroxy telechelics havingisocyanate-reactive hydroxyl end-groups on opposing termini. All polyoltelechelics are polyols, which also include monomers, dimers, trimers,adducts, and the like having two or more hydroxyl groups.

In another example, the reaction product can be a polyurea formed from apolyurea prepolymer and a curative, the polyurea prepolymer being areaction product of a polyamine telechelic and an isocyanate. Thepolyamine telechelic comprises at least two terminal amine end-groupsthat are independently primary or secondary. The polyamine telecheliccan further comprise additional amine groups that are independentlyprimary or secondary, and are independently located at the termini,attached directly to the backbone as pendant groups, located within thebackbone, or located within pendant moieties that are attached to thebackbone. The secondary amine moieties may in part form single-ring ormulti-ring heterocyclic structures having one or more nitrogen atoms asmembers of the rings. The polyamine telechelic can be α,ω-aminotelechelics having isocyanate-reactive amine end groups on opposingtermini. All polyamine telechelics are polyamines, which also includemonomers, dimers, trimers, adducts, and the like having two or moreamine groups.

In a further example, the reaction product can be a poly(urethane-urea)formed from a poly(urethane-urea) prepolymer and a curative. Thepoly(urethane-urea) prepolymer can be a reaction product of anisocyanate and a blend of polyol and polyamine telechelics.Alternatively, the poly(urethane-urea) prepolymer can be a reactionproduct of an aminoalcohol telechelic and an isocyanate. Theaminoalcohol telechelic comprises at least one primary or secondaryterminal amine end-group and at least one terminal hydroxyl end-group.The polyamine telechelic can further comprise additional amine and/orhydroxyl groups that are independently located at the termini, attacheddirectly to the backbone as pendant groups, located within the backbone,or located within pendant moieties that are attached to the backbone.The secondary amine moieties may in part form single-ring or multi-ringheterocyclic structures having one or more nitrogen atoms as members ofthe rings. The aminoalcohol telechelic can be α-amino-ω-hydroxytelechelics having isocyanate-reactive amine and hydroxyl end groups onopposing termini. All aminoalcohol telechelics are aminoalcohols, whichalso include monomers, dimers, trimers, adducts, and the like having atleast one amine group and at least one hydroxyl group.

Any one or combination of two or more of the isocyanate-reactiveingredients disclosed herein can react with stoichiometrically deficientamounts of polyisocyanate such as diisocyanate to form elastomers thatare substantially free of hard segments. Such elastomers can have rubberelasticity and wear resistance and strength, and can be millable.

Polyamine Telechelics

Polyamine telechelics have two, three, four, or more amine end-groupscapable of forming urea linkages (such as with isocyanate groups), amidelinkages (such as with carboxyl group), imide linkages, and/or otherlinkages with other organic moieties. As such, polyamine telechelics canbe reacted with polyacids to form amide-containing polyamine or polyacidtelechelics, be reacted with isocyanates to form polyurea prepolymers,and be used as curatives to cure various prepolymers. Any one or more ofthe hydrogen atoms in the polyamine telechelic (other than those in theterminal amine end-groups) may be substituted with halogens, cationicgroups, anionic groups, silicon-based moieties, ester moieties, ethermoieties, amide moieties, urethane moieties, urea moieties,ethylenically unsaturated moieties, acetylenically unsaturated moieties,aromatic moieties, heterocyclic moieties, hydroxy groups, amine groups,cyano groups, nitro groups, and/or any other organic moieties. Forexample, the polyamine telechelics may be halogenated, such as havingfluorinated backbones and/or N-alkylated fluorinated side chains.

Any polyamine telechelics available or known to one of ordinary skill inthe art are suitable for use in compositions of the present disclosure.The M_(w) of the polyamine telechelics can be about 100-20,000, such asabout 150, about 200, about 230, about 500, about 600, about 1,000,about 1,500, about 2,000, about 2,500, about 3,000, about 3,500, about4,000, about 5,000, about 8,000, about 10,000, about 12,000, about15,000, or any M_(w) therebetween. The polyamine telechelic can compriseone or more hydrophobic and/or hydrophilic segments.

a) Polyamine Polyhydrocarbons

An example of polyamine polyhydrocarbons has a generic structure of:

where R₁ and R₂ are independently chosen from hydrogen, alkyl, aryl,aralkyl, alicyclic, cycloalkyl, and alkoxy groups; R₃, R₄, and R₅ areindependently chosen from linear, branched, cyclic (includingmonocyclic, aromatic, bridged cyclic, spiro cyclic, fused polycyclic,and ring assemblies), saturated, unsaturated, hydrogenated, and/orsubstituted hydrocarbon moieties having 1 to about 30 carbon atoms; x,y, and z are independently zero to about 200, and x+y+z≧2. R₁ and R₂ canbe linear or branched structures having about 20 carbon atoms or less,such as 1-12 carbon atoms. R₃, R₄, and R₅ can independently have thestructure C_(n)H_(m), where n is an integer of about 2-20, and m is zeroto about 40. Any one or more of the hydrogen atoms in R₁ to R₅ may besubstituted with halogens, cationic groups, anionic groups,silicon-based moieties, ester groups, ether groups, amide groups,urethane groups, urea groups, ethylenically unsaturated groups,acetylenically unsaturated groups, hydroxy groups, amine groups, or anyother organic moieties. R₁ and R₂ can be identical. At least one of R₃,R₄, and R₅ can have the structure C_(n)H_(2n), n being an integer ofabout 2-12, and x+y+z is about 5-100.

The polyamine polyhydrocarbon can have one of the following structures:

where x is the chain length, i.e., 1 or greater; n is about 1-12; and Ris alkyl group having 1 to about 20, such as 1-12, carbon atoms, aphenyl group, a cyclic group, or mixture thereof.

Polyamine polyhydrocarbons are hydrophobic in general, and can providereduced moisture absorption and permeability to the resultingcompositions. Non-limiting examples of polyamine polyhydrocarbonsinclude α,ω-diamino polyolefins such as α,ω-diamino polyethylenes,α,ω-diamino polypropylenes, α,ω-diamino polyethylenepropylenes,α,ω-diamino polyisobutylenes, α,ω-diamino polyethylenebutylenes (withbutylene content of at least about 25% by weight, such as at least 50%),amine-terminated Kraton rubbers; α,ω-diamino polydienes such α,ω-diaminopolyisoprenes, partially or fully hydrogenated α,ω-diaminopolyisoprenes, amine-terminated liquid isoprene rubbers, α,ω-diaminopolybutadienes, partially and/or fully hydrogenated α,ω-diaminopolybutadienes; as well α,ω-diamino poly(olefin-diene)s such asα,ω-diamino poly(styrene-butadiene)s, α,ω-diaminopoly(ethylene-butadiene)s, and α,ω-diaminopoly(butadiene-styrene-butadiene)s.

One group of polyamine polyhydrocarbons is polyamine polyalkyleneshaving a plurality of secondary or tertiary amine moieties, such asthose having the formula R′HN—(R—N(R′))_(n)—H, where R is the same ordifferent alkyl, aryl, aralkyl, alicyclic, cycloalkyl, and alkoxygroups; R′ is the same or different moieties chosen from hydrogen,alkyl, aryl, aralkyl, alicyclic, cycloalkyl, and alkoxy groups; n isabout 5 or greater, such as about 10 or greater. R and R′ canindependently have 1 to about 20 carbon atoms, such as 1-12 carbonatoms, or about 1-4 carbon atoms.

Another group of polyamine polyhydrocarbons is polyamine polydienes,which also include polyamine poly(alkylene-diene)s, as well as blendsthereof. Suitable polyamine polydienes have M_(n) of about 1,000-20,000,such as about 1,000-10,000, or about 3,000-6,000, and an aminefunctionality of about 1.6-10, such as about 1.8-6, or about 1.8-2. Thediene monomers can be conjugated dienes such as 1,3-butadiene, isoprene,2,3-dimethyl-1,3-butadiene, and mixtures thereof. The polyaminepolydiene can be substantially hydrogenated to improve stability, suchthat at least about 90%, or at least about 95%, of the carbon-carbondouble bonds in the polydiene are hydrogenated.

The elastomer compositions of the present disclosure can be resilient.Resilience can be measured, for example, by determining the percentageof the original height to which a ½″ steel ball will rebound after beingdropped onto an immobilized ½″ thick elastomer sample from a height ofone meter. A resilient elastomer can display a rebound height percentageof greater than 60%, such as greater than about 70%, or greater thanabout 75%.

Diamino polydienes and diamino copolydienes, among other polyaminetelechelics, are capable of imparting high resiliency in thecompositions. The diamino polydiene can be diamino polybutadiene having1,4-addition of about 30-70%, such as about 40-60%. The diaminopolybutadiene can have 1,2-addition of at least about 40%, such as about40-60%. The hydrogenated diamino polybutadiene can remain liquid atambient temperature. In one example, the diamino polybutadiene can bemore than about 99% hydrogenated, having M_(n) of about 3,300, an aminefunctionality of about 1.92, and a 1,2-addition content of about 54%. Inanother example, the diamino polydiene can be diamino polyisoprenehaving 1,4-addition of at least about 80% and moderate glass transitiontemperature and viscosity.

One group of diamino copolydienes has a generic structure of:

where R₁ and R₂ are independently chosen from hydrogen, alkyl, aryl,aralkyl, alicyclic, cycloalkyl, and alkoxy groups; R₃ is hydrogen,linear or branched alkyl group (such as methyl or t-butyl), cyano group,phenyl group, halide, or a mixture thereof; R₄ is hydrogen, linear orbranched alkyl group, halide (such as chloride or fluoride), or amixture thereof; x and y are independently about 1-200. R₁ and R₂ can belinear or branched, having about 20 carbon atoms or less, such as 1-12carbon atoms. The y:x ratio can be about 82:18 to about 90:10. Thediamino copolydiene can be substantially hydrogenated (i.e.,substantially all of the >C══CH— or >C══CH₂ moieties are hydrogenatedinto >CH—CH₂— or >C—CH₃ moieties, respectively). One example can behydrogenated diamino poly(acrylonitrile-co-butadiene) where R₃ is cyanogroup and R₄ is hydrogen.

Polyamine polyhydrocarbons can also be derived from polyolpolyhydrocarbons through means such as amination, or reaction withaminoalcohols, amino acids, or cyclic amides. For example, polyolpolyhydrocarbons can be end-capped with 2-, 3-, and/or 4-aminobenzoicacid and the likes thereof as disclosed herein to form aminobenzoatederivatives, e.g., polymethylene-di-p-aminobenzoates.

b) Polyamine Polyethers

An example of the polyamine polyethers has a generic structure of:

Commercial examples of polyamine polyethers include, but are not limitedto, polyoxyethylene diamines, polyoxypropylene diamines (such asJeffamine® D2000 from Huntsman Corporation, Austin, Tex.),α,ω-bis(2-aminopropyl)polyoxypropylenes (such as those having M_(w)about 200-5,000), polyoxytetramethylene diamines, modifiedpolyoxytetramethylene diamines, poly(oxyethylene-oxypropylene) diamines,α,ω-bis(3-aminopropyl)polytetrahydrofurans (such as those having M_(w)about 200-2,000), poly(oxyethylene-capped oxypropylene) diamines,poly(oxybutylene-oxypropylene-oxyethylene) diamines, polyoxyalkylenediamines initiated by bisphenol A or primary monoamines, tri-blockpolyether polyamines such aspoly(oxypropylene-block-oxyethylene-block-oxypropylene) diamines andpoly(oxyethylene-block-oxypropylene-block-oxyethylene) diamines,polyoxypropylene triamines initiated by glycerin, trimethylolethane, ortrimethylolpropane, polyoxypropylene tetramines initiated bypentaerythritol, ethylene diamine, phenolic resin, or methyl glucoside,diethylenetriamine-initiated polyoxypropylene pentamines,sorbitol-initiated polyoxypropylene hexamines, and sucrose-initiatedpolyoxypropylene octamines. Other suitable polyether polyamines includethose disclosed in co-pending application Ser. No. 10/434,739.

In one example, the polyamine polyether has the structure of (3), whereR₃ and R₅ are the same linear, branched, or cyclic radicals having atleast about 10 carbon atoms, such as at least about 18 carbon atoms, orat least about 30 carbon atoms, and y and z are zero, so that thegeneric structure becomes R₁HN—[R₃—O]_(x)—R₃—NHR₂, where R₁ to R₃ are asdescribed above. In one example, R₃ is an alkylene moiety, while x isabout 1-50, such as about 1.5-30. These polyamine polyethers can behighly hydrophobic. When x is about 10 or less, such as 1.5, 2, 4, 5, 7,or any number therebetween, these polyamine polyethers are typicallyliquid at ambient temperature, having a viscosity at 25° C. of about3,000-12,000 cP. The hydrophobicity of such polyamine polyethers canenhance hydrolysis resistance of the compositions and reduce moistureabsorption.

In another example, the polyamine polyether has the structure of (3),where R₅ and R₆ are identical, R₄ and R₅ are the same or differentalkylene groups having about 2-40 carbon atoms, such as about 2-20carbon atoms, or about 2-10 carbon atoms, or about 2-4 carbon atoms, R₃is a backbone of a dimer diol, fatty polyol, or oleochemical polyols asdisclosed herein below, x is 1, and 40≧(y+z)≧1. As such, the structure(3) becomes R₁HN—[R₄—O]_(y)—R₃—[O—R₅]_(z+1)—NHR₂, where R₁ to R₅ are asdescribed above. These polyamine polyethers are hydrolysis-resistant,and typically have M_(n) of about 600-3,000.

To enhance resilience of the compositions of the present disclosure, thehydroxy-terminated and/or amine-terminated polymers as described hereincan have oxyethylene moieties at the terminals, such as in directattachment with the amine and/or hydroxyl end-groups, and the content ofthe terminal oxyethylene moieties can be about 5-30% by weight of thepolymer. The oxyethylene moieties can be added to hydroxy-terminatedand/or carboxyl-terminated polymers via ring-opening polymerization ofethylene oxide with an alkali catalyst such as alkali metal, alkalimetal hydroxide, alkali metal alkoxide, and double metal cyanidecomplex.

For resilient elastomer compositions, a blend of two polyaminepolyethers can be used to react with isocyanate and form the prepolymer,wherein the first polyamine polyether has a first molecular weight ofabout 3,500-6,500, a first amine functionality of about 3 or less, and afirst oxyethylene content of about 8-20% by weight, while the secondpolyamine polyether has a second molecular weight of about 4,000-7,000,a second amine functionality of about 4-8, and a second oxyethylenecontent of about 5-15% by weight. The first polyamine polyether mayconstitute about 70-98% by weight of the blend, while the secondpolyamine polyether may constitute about 2-30% by weight of the blend.Alternatively, a mixture having about 25-95% of the polyamine polyetherblend and about 5-75% of at least a third polyamine telechelic differentfrom the first and second polyamine polyethers is also suitable toformulate a resilient elastomer composition.

In another resilient composition, the polyamine telechelic is apolyether triamine having M_(n) of about 4,500-6,000 and an averageamine functionality of about 2.4-3.5, such as about 2.4-2.7. In afurther resilient example, the polyamine polyether may have a weightaverage unsaturation of about 0.03 meq/g or less (measured by ASTMD-2849-69), such as about 0.02 meq/g or less, or about 0.015 meq/g orless, or about 0.01 meq/g or less, and M_(n) of about 1,500-5,000. Thepolyamine polyether may comprise at least one randompoly(oxyethylene-oxyalkylene) terminal block or polyoxyethylene terminalblock, with an oxyethylene content of about 12-30% by weight. Lowunsaturation in the polyamine polyethers of about 0.002-0.007 meq/g isachieved by using double metal cyanide catalysts when forming thepolyether backbone. Concomitant to the low unsaturation, the polyaminepolyethers may also have a low polydispersity of about 1.2 or less.

In a further example, the polyamine polyether can have repeatingbranched oxyalkylene monomer units derived from branched diol monomers,chiral diol monomers, alkylated cyclic ethers, and/or chiral cyclicethers, through homo-polymerization, co-polymerization, and/orring-opening polymerization. The polyamine polyethers can be obtained byaminating polyol polyethers formed from chiral diol/ether and achiraldiol/ether at a molar ratio of about 85:15 to about 20:80. Anon-limiting example of such polyol polyethers is referred to as amodified polytetramethylene ether glycol (“PTMEG”) diamine, or anamine-terminated poly(tetrahydrofuran-co-methyltetrahydrofuran) ether.

The main carbon chain can be directed attached to at leastone, such as two or more, isocyanate-reactive amine functionality, whichcan be primary and/or secondary. The fatty polyamines can be monomerdiamines, dimer diamines or trimer triamines derived from fattypolyacids disclosed herein, using textbook techniques such as byreacting the dimerized fatty acids with ammonia to obtain thecorresponding dimerized fatty nitriles which may then be hydrogenated toform the dimer diamines.

Alkylene polyamines such as ethylene polyamines can be a complex mixtureof polyalkylene polyamines including cyclic condensation products. Theterm “polyalkylene polyamine” as employed herein is intended to includepolyalkylene polyamines in pure or relatively pure form, mixtures ofsuch materials, and crude polyalkylene polyamines, which may containminor amounts of other compounds. Other useful types of polyaminemixtures are those resulting from stripping of the polyalkylenepolyamine mixtures to leave, as residue, what is often termed “polyaminebottoms.” In general, alkylene polyamine bottoms can be characterized ashaving less than 2%, usually less than 1% (by weight) material boilingbelow about 200° C. These alkylene polyamine bottoms include cycliccondensation products such as piperazine and higher analogs ofdiethylenetriamine, triethylenetetramine and the like. These alkylenepolyamine bottoms may be reacted solely with the acylating agent or theymay be used with other amines, polyamines, or mixtures thereof.

Non-limiting examplesinclude triethylenetetramine (TETA), tetraethylenepentamine (TEPA),pentaethylenehexamine (PEHA), and mixtures of polyamines such as thealkylene polyamine bottoms. The condensation reaction can be conductedat about 60-265° C., such as about 220-250° C., in the presence of anacid catalyst.

j) Sterically Hindered Polyamines

Conventional polyamines can be fast reacting with isocyanates. In orderto extend the pot-life of the composition and improve processability,polyamine reactivity may be moderated by sterically hinder the reactiveamine groups. For example, 4,4′-bis-(sec-butylamino)-dicyclohexylmethaneand N,N′-diisopropyl-isophorone diamine are secondary diamines havingmoderated reactivity.

One or more or all of the reactable amine groups within the polyaminecompound can be sterically hindered, so that the polyamine compound canprovide the combination of reduced reactivity toward isocyanate groups,and improved chemical stability toward actinic radiations such as UVlight. Sterically hindered NCO group can have the following structure:

where C₁, C₂, and C₃ are independent tertiary (i.e., methine) orquaternary carbon atoms, and R is as defined above. One, two, or allthree of C₁, C₂, and C₃ can be free of C—H bonds. C₁, C₂, and C₃ may inpart form a substituted ring structure having about 4-30 carbon atoms.The ring structure may be saturated, unsaturated, aromatic, monocyclic,polycyclic (e.g., bicyclic, tricyclic, etc.), or heterocyclic having oneor more O, N, or S atoms. The ring structure may have one, two, three,or more moieties of the above structure, while the polyamine compoundmay have one, two, or more of such ring structures. For example,sterically hindered polyamine may have a structure of:

where Z₁ to Z₈ are independently chosen from halogenated orun-halogenated hydrocarbon moieties having about 1-20 carbon atoms,halogenated or un-halogenated organic moieties having at least one O, N,S, or Si atom and zero to about 12 carbon atoms, or halogens; Y₁ to Y₄are independently chosen from hydrogen, halogenated or un-halogenatedhydrocarbon moieties having about 1-20 carbon atoms, halogenated orun-halogenated organic moieties having at least one O, N, S, or Si atomand zero to about 12 carbon atoms, and halogens; Z is halogenated orun-halogenated hydrocarbon moieties having about 1-60 carbon atoms, orhalogenated or un-halogenated organic moieties having at least one O, N,S, or Si atom and zero to about 60 carbon atoms. Z can have one of thefollowing structures:

where A₁ to A₃ are independently chosen from halogenated orun-halogenated hydrocarbon moieties having about 1-36 carbon atoms, andhalogenated or un-halogenated organic moieties having at least one O, N,S, or Si atom and zero to about 30 carbon atoms. Any one or more, or allof Z₁ to Z₈ can be hydrogen. As a non-limiting example, Z may be—C(CH₃)₂—. Other non-limiting examples include 1,4-durene diamine,2,3,5,6-tetramethyl-1,4-diaminocyclohexane, and:

where R is the same or different, chosen from hydrogen and linear orbranched C₁-C₆ alkyl groups, such as methyl, ethyl, propyl, butyl,pentyl, hexyl, iso-propyl, iso-butyl, sec-butyl, neo-pentyl, and maleategroups.

Sterically hindered polyamines can also have a generic structure of:

where R₁, R₂ and Z₁ to Z₄ are independently chosen from hydrogen andorganic moieties having about 1-60 carbon atoms, such as about 1-20,about 1-12, or about 1-6 carbon atoms. Suitable organic moieties can belinear or branched, saturated or unsaturated, aliphatic, alicyclic,aromatic, or araliphatic, halogenated or otherwise substituted,optionally having one or more heteroatoms such as O, N, S, or Si, andinclude hydrocarbon moieties such as alkyl, alkyloxy, alkylthio, oralkylsilyl moieties. NHR, and NHR₂ can be in ortho, meta, or parapositions with respect to one another. One or more of Z₁ to Z₄ can beNHR₃, where R₃ is analogous to R₁ and R₂.

In one example, R₁ and R₂ are both hydrogen, and at least one of Z₁ toZ₄, such as two or more thereof, is/are the organic moieties describedabove, having 2 or more carbon atoms, or being branched and having 3 ormore carbon atoms. In another example, at least one of R₁ and R₂ can bethe organic moiety other than hydrogen, having 2 or more carbon atoms,such as being branched and having 3 or more carbon atoms. In a furtherexample, at least one of R₁, R₂, and Z₁ to Z₄ can have one or moreprimary or secondary amine groups, such as one or more primary amineend-groups distal to the ring structure. In yet another example, thesterically hindered polyamine can be regioselective; that is, at least afirst amine group has a reactivity different from that of a second aminegroup, all else being equal. The regioselectivity may result fromdifference in steric interference around the two different amine groups(i.e., steric asymmetry). Scenarios which may result in regioselectivityinclude: a) the first amine is secondary, while the second amine isprimary; b) the first amine is sterically hindered by one or moreortho-positioned organic moieties, on one side or both sides, while thesecond amine has none; or c) the first amine is sterically hindered bytwo or more ortho-positioned organic moieties on both sides, while thesecond amine has only one ortho-positioned organic moiety.

Z may be as small as O or CH₂, orcomprise polymeric chains such as polyhydrocarbon, polyether, polyester,polyamide, polycarbonate, polyacrylate, polysiloxane, and copolymerchains thereof. Alternatively, Z may comprise at least two ester and/oramide linkages.

In one example, R is hydrogen, at least one of Z₁ to Z₄, such as two ormore thereof, is/are the organic moieties described above, such ashaving two or more carbon atoms, or branched having 3 or more carbonatoms, and is/are ortho to NHR. In another example, each NHR is anortho- or meta-substituent with respect to Z. In a further example, atleast one R is an organic moiety, such as having 2 or more carbon atoms,or branched having 3 or more carbon atoms. In yet another example, atleast one of R and Z₁ to Z₄ has one or more primary or secondary aminegroups, such as at least one primary amine end-group distal to the ring.In still another example, the sterically hindered polyamine isregioselective, having one of the following scenarios: i) a first NHR issecondary, while a second NHR is primary; ii) the first NHR issterically hindered by one or more ortho-positioned organic moieties onone side or both sides, while the second NHR has none; or iii) the firstNHR is sterically hindered by two or more ortho-positioned organicmoieties one both sides, while the second NHR has onlyone-ortho-positioned organic moiety.

Thepolyether backbone can be prepared by acid-catalyzed polycondensation ofsuitable low molecular weight alkylene glycols such as dimer diols atelevated temperature (e.g., 150-250° C.). These polyol polyethers can behydrophobic. When x is less than about 10, such as about 1.5-7, likeabout 2, about 4, or about 5, these polyol polyethers can be liquid atambient temperature, having a viscosity at 25° C. of about 3,000-12,000cP.

The first polyol polyether canconstitute about 70-98% by weight of the blend, and the second polyolpolyether can constitute about 2-30% by weight of the blend. A mixturehaving about 25-95% by weight of this polyol polyether blend and about5-75% by weight of at least a third polyol telechelic different from thefirst and second polyether polyols is also suitable to formulate aresilient elastomer composition.

In a further example, the polyol polyether comprises atleast one random poly(oxyethylene-oxyalkylene) terminal block orpolyoxyethylene terminal block, having oxyethylene moieties in theamount of about 12-30% by weight of the polyol polyether. Low level ofaverage unsaturation of about 0.002-0.007 meq/g is achieved in thepolyol polyether by using double metal cyanide catalysts when formingthe polyether backbone. The polyol polyethers can also have a lowpolydispersity of about 1.2 or less.

The polyol polyether can have repeating branched oxyalkylene monomerunits derived from branched diol monomers, chiral diol monomers,alkylated cyclic ethers, and/or chiral cyclic ethers, throughhomo-polymerization, co-polymerization, and/or ring-openingpolymerization, optionally in combination with a second diol or cyclicether. As a non-limiting illustration, the chiral diol may be2-methyl-1,4-butanediol; the chiral cyclic ether may be2-methyl-tetrahydrofuran; the second diol may be 1,4-butanediol(achiral); and the second cyclic ether may be tetrahydrofuran (achiral).Other chiral diols include 2,4-petanediol and 3-methyl-1,3-butanediol.Exemplary linear and branched oxyalkylene monomer units include, but arenot limited to, —O—CH₂—CH(CH₃)—(CH₂)₂—, —O—(CH₂)₃—, —O—(CH₂)₂—,—O—C(CH₃)₂—CH₂—, —O—(CH₂)₂—CH(CH₃)—CH₂—, —O—CH₂—CH(CH₃)—,—O—CH(CH₂CH₃)—CH₂—, —O—CH₂—CH(CH₃)—CH₂—, —O—(CH₂)₃—CH(CH₃)—,—O—CH₂—C(CH₃)₂—, —O—CH(CH₃)—CH₂—, —O—(CH₂)₅—, —O—CH₂—CH(CH₂CH₃)—,—O—CH(CH₃)—(CH₂)₃—, —O—(CH₂)₄—, —O—CH(CH₃)—(CH₂)₂—, and—O—(CH₂)₂—CH(CH₃). The polyol polyether can be obtained bycopolymerizing chiral diol/ether and achiral diol/ether at a molar ratioof about 85:15 to about 20:80. A non-limiting example of such polyetherpolyols is referred to as a modified PTMEG diol, or an α,ω-dihydroxypoly(tetrahydrofuran-co-methyltetrahydrofuran) ether.

Oleochemical polyol telechelics are often derivedfrom natural fats and oils which, if not having hydroxyl groups already,can have double bonds and/or carboxyl groups that may be converted intohydroxyl groups. Double bonds on fatty acids can be epoxidized byhydrogen peroxide to form multiple oxirane functionalities. Theseepoxidized fats and oils can be liquid at ambient temperature, and canbe used as phthalate-free, non-volatile, extraction and migrationresistant plasticizers/stabilizers, as polymer building blocks fornon-urethane compositions (e.g., linoleum, synthetic leather), or ascrosslinking agents for hydroxyl- and/or carboxyl-terminated polymers(e.g., polyesters, polyurethane, polyacrylate resins). They can bereacted with low molecular weight mono- and/or polyfunctional alcohols,acids, and/or or hydroxy acids to form ether polyols and/or esterpolyols, which may or may not contain oxirane groups (i.e., throughincomplete or complete reactions, respectively). Fatty polyoltelechelics derived as such can be liquid, of relatively low molecularweight, and may have reactive hydroxyl groups in the ester positionsonly (i.e., fatty acid polyol esters like glycerol monostearate), in thehydrocarbon chain only (i.e., fatty acid polyol esters of monofunctionalalcohols), or both (i.e., fatty acid polyol esters such as ricinoleicacid monoglyceride). These fatty polyol telechelics can be free oftriglyceride ester linkages.

One form of adduct polyol telechelics can be dimer diols, which can bealiphatic α,ω-diols having relatively high molecular weight. Dimer diolscan be produced by polymerization (e.g., dimerization) of one or moremonounsaturated and/or polyunsaturated fatty monoalcohols, such aspalmitoleyl, oleyl, elaidyl, linolyl, linolenyl and/or erucyl alcohols.The resulting dimer diols can be mixtures having a major content (e.g.,greater than about 50% by weight of the mixture) of dimer diols andrelatively minor contents (e.g., less than about 30%) of the monomeralcohols, trimers, and/or higher oligomers.

Dimer diols can also be prepared from dimer diacids and/or estersthereof, including dimethylesters and hydroxy acid methylesters, such asthose disclosed herein, by means of hydrogenation or condensation withpolyols (e.g., ethylene glycols) and/or polyacids (e.g., azelaic acids).The former can yield hydrocarbon polyol telechelics, whereas the latercan yield polyol polyesters. Starting from a distilled dimer diacid,hydrogenation can produce dimer diols having a dimer content of greaterthan about 90%, such as greater than about 95% by weight. The resultingdimer diols may be unsaturated, partly hydrogenated, or completelyhydrogenated (i.e., fully saturated). Likewise, castor oil can produce,through hydrolysis, esterification or transesterification, andhydrogenation, 12-hydroxystearyl alcohol having one primary and onesecondary hydroxyl group and a relatively high molecular weight.

Non-limiting dimer diols can have one of the following structures:

where x+y and m+n are both at least about 8, such as at least about 10,such as 12, 14, 15, 16, 18, 19, or greater.

Molecular weight of fatty polyol telechelics can be about 200-15,000,such as about 250-12,000, or about 500-5,000. Fatty polyol telechelicscan be liquid at room temperature, having low to moderate viscosity at25° C. (e.g., about 100-10,000 cP or about 500-5,000 cP). It ispostulated that highly branched polyols in general has desirableresistance to hydrolysis. As such, the fatty polyol telechelics can bebranched, such as with alkyl groups, thereby displaying improvedchemical stability, improved color stability (i.e., reduced yellowingbecause of reduction or elimination of unsaturation), high mechanicalstrength and durability, suitable in forming soft segments, and informulating solvent-free two pack full solid polyurethane/polyureacompositions. Because of their fluidity, these fatty polyol telechelicscan be used as reactive diluents in solvent-borne polyurethane/polyureacompositions to achieve higher solid content. Conventional volatilesolvents such as xylene, butyl acetate, methoxy propylacetate, ethoxypropylacetate may still be necessary to improve compatibility of resinand polyisocyanate, avoid phase separation, and adjust viscosity, butthe level of these non-reactive diluents can be significantly reduced.

j) Acid-Catalyzed Polyol Telechelics

Polyols and/or polyol telechelics of the present disclosure can bepolymerized into new polyol telechelics through, for example, acidcatalyzed dehydration. The condensation reaction can take place atelevated temperatures of at least about 150° C., and up to about200-250° C., and under normal pressure. The acid catalysts include, butare not limited to, sulfuric acid, hydrochloric acid, methane sulfonicacid, methane disulfonic acid, butane sulfonic acid, perfluorobutanesulfonic acid, benzene sulfonic acid, benzene disulfonic acid, toluenesulfonic acid, naphthalene disulfonic acid, methionic acid, phosphoricacid, perchloric acid, boron trifluoride, zinc chloride, quinolinehydrochloride, alkali metal hydrogen sulfates, other organic sulfonicacids, other aromatic sulfonic acids, other acidic salts, other readilyhydrolysable salts, other dissociating salts, acidic ion exchangerscontaining sulfonic acid group, and acidic aluminas. These catalysts canbe used individually or in combination of two or more thereof, in aquantity of about 0.1-30%, such as about 0.2-2% or about 0.5-15%, byweight of the starting polyols and/or polyol telechelics. Thecondensation reaction takes about 2-20 hours, such as about 6-12 hours,until the theoretically calculated quantity of water is obtained in thewater separator. The catalysts are hydrolyzed and precipitated out withaqueous alkali or ammonia. Solvents, unreacted starting materials,by-products such as ring ethers, and water are removed by azeotropicdistillation, evaporation in vacuo, and/or other conventional means. Thereaction product can be purified through distillation or fractionaldistillation.

The starting polyols and/or polyol telechelics include, but are notlimited to, 1,5-pentanediol, 3-methyl-1,5-pentanediol, 1,6-hexanediol,1,7-heptanediol, 1,8-octanediol, 1,9-nonanediol, 1,10-decanediol, dimerdiols, and other aliphatic diols. In one example, one of these diols byweight of at least about 50% can be blended with one or more of theother diols as the starting material. The reaction product can have astructure of HO—[R—O—]_(n)H, where R is a linear or branched alkyleneradical having about 5 carbon atoms or more, such as about 8, about 10,about 12, about 16, about 18, about 20, about 30, about 36, about 44,and about 54 carbon atoms or more; and n is more than 1, such as about 2or more. The main chain of R can have at least about 5 carbon atoms,such as about 8 or about 10 carbon atoms or more. The terminal hydroxylgroups can be primary. For molecularly non-uniform polyol polyethers,the number n can be about 0.5-5, such as 1.5-5. For molecularly uniformpolyol polyethers, the number n can be about 2-10, such as about 4-7.The reaction product can have a hydroxyl number of less than 750, suchas about 600, about 450, about 250, or about 175 or less, or about10-100, or any number therebetween. The reaction product can have anacid value of less than 5, such as about 1-3. The hydroxyl number is themilligrams of KOH equivalent to the quantity of acetic acid bound by 1 gof the reaction product during an acetylation reaction. The reactionproduct is boiled with acetic anhydride/pyridine and the acid formed isfiltered with KOH solution. The acid value is a measure of the contentof free organic acids in the reaction product. It indicates the numberof milligrams of KOH used to neutralized 1 g of the reaction product.The reaction product can have a viscosity at 25° C. of about 3,000 cP orgreater, such as about 3,800-12,000 cP, and a solubility in 100 ml ofwater at 20° C. of about 1 mg or less, such as about 0.1 mg or less.

Polyol telechelics of the present disclosure, such as polyolpolyhydrocarbons, polyol polyethers, fatty polyol telechelics (such asdimer diols), and/or acid-catalyzed polyol telechelics as describedabove can be randomly copolymerized into new polyol telechelics throughtransesterification with carbonate-forming compounds at temperatures ofabout 120-220° C., such as about 130-200° C., under pressures of about0.1-200 mbar, such as about 0.1-100 mbar, over a period of about 6-20hours. The reaction may be catalyzed by bases or transition metalcompounds. By-products of the reaction can be moved via distillation.

The starting polyol telechelic can have a relatively low molecularweight, such as 150, 180, 300, 400, 5,00, 700, 800, 1,000, and anynumber therebetween. The starting polyol telechelic can be of a singlemolecular species, or a blend of two or more suitable polyoltelechelics. One polyol telechelic can be present in an amount of50-100% by weight.

Materials and methods used toproduce such polyol polyethercarbonates are disclosed in U.S. Pat. Nos.4,808,691 and 5,621,065, which are incorporated herein by reference.

l) Derivatized Polyol Telechelics

Polyol telechelics can be derived from corresponding polyacids and alkyl(such as methyl) esters thereof, such as through hydrogenation. Anycarboxylic acid terminated polymers known and/or available to oneskilled in the art, including the fatty polyacids and polyacid adductsdisclosed herein, may be converted to polyol telechelics. Other polyoltelechelics can be derived from suitable polymers, optionally having twoor more functionalities such as amine, hydroxyl, carbonyl, etc., throughreactions with polyols, aminoalcohols, hydroxy acids or esters thereof,cyclic ethers, and/or cyclic esters. For example, polyol telechelics canbe derived from polyamine telechelics or other polyol telechelics viareactions with cyclic esters, hydroxy acids, and/or hydroxy esters, inwhich multiple amide linkages or esters linkages, respectively, areformed.

One example of polyetherester polyols have a generic structure of:

where R₃ to R₄ are independently chosen from hydrogen, alkyl, aryl,aralkyl, alicyclic, cycloalkyl, or alkoxy moieties having about 1-60carbon atoms, such as about 1-20 carbon atoms; R₅ is a hydrogen, alkylgroup (such as methyl), phenyl group, halide, or mixture thereof, n isabout 1-12; and x is about 1-200. These polyetherester polyols can beobtained from polyol polyethers through means such as reaction withhydroxy acids or cyclic esters. Other polyetherester polyols can beformed from polyacid telechelics by reacting with polyols and/or cyclicesters.

One group of derivatized polyol telechelics can be prepared by addingcyclic ethers to the termini of an existing polyol telechelic. Forexample, the existing polyol telechelic can be any of the polyoltelechelics disclosed herein, such as one or a blend of the fatty polyoltelechelics, and the cyclic ethers can be one or more of those havingabout 2-14 carbon atoms, such as ethylene oxide, propylene oxide,butylene oxide, tetrahydrofuran, and cyclic ethers having 5 or morecarbon atoms. Known methods may be used to add the cyclic ethers to thepolyol telechelic. For example, the hydroxyl groups in the polyoltelechelic can be converted to alcoholate by heating with alkalihydroxide (such as NaOH or KOH) at about 100-140° C., which is thenmixed with the cyclic ether (such as those having a 3-membered ring) toinitiate an anionic polymerization. Alternatively, the cyclic ether(such as those having a 5-membered ring) is subjected to a cationicring-opening polymerization at about 0° C., in the presence of catalystssuch as boron trifluoride ether salt, and then mixed with alkali saltsof the polyol telechelic (such as disodium salt of the dimer diol) toterminate the polymerization and yield the derivatized polyoltelechelic.

The resulting polyol telechelic can have a structure ofHO—(Y—O)_(m)—X—O—(Z—O)_(n)—H, where X is the backbone of the startingpolyol telechelic HO—Z—OH; Y is the organic moiety of cyclic ether

Z is the organic moiety of cyclic ether

m and n are the same or different numbers of 0 or more, and m+n is about2-100, such as about 2-40. Y and Z can be the same or different, and canhave 2 or more carbon atoms or 5 or more carbon atoms. Y and Z canindependently have one or more heteroatoms such as O, S, N, and Si. Theresulting polyol telechelic can have a hydroxyl number of about 200 orless, such as about 140 or less. The molecular weight of segment Z—O canbe at least about 1% by weight of the M_(w) of the polyol telechelic,the latter of which can be about 500-20,000, such as about 600, about1,000, about 2,000, about 3,000, about 5,000, about 8,000, about 10,000,about 12,000, about 15,000, and any number therebetween. When certaincyclic ethers such as propylene oxide and butylene oxide are used, thehydroxyl groups of the resulting polyol telechelics may be secondary,which can be converted to primary for improved reactivity. These andother polyol telechelics as described in U.S. Pat. No. 6,252,037 areincorporated herein by reference.m) Ethylenically and/or Acetylenically Unsaturated Polyol Telechelics

Any of the polyol telechelics disclosed herein above may comprise one,two, or a plurality of ethylenic and/or acetylenic unsaturationmoieties. These unsaturation moieties can be used to form carbon-carbonand/or ionic crosslinks in combination with vulcanizing agents (i.e.,radical initiators, polyisocyanates, co-crosslinking agents, curativescomprising ethylenic and/or acetylenic unsaturation moieties, and/orprocessing aids). These unsaturation moieties may be pendant along thebackbone of the polyol telechelics, attached to pendant groups or chainsbranched off the backbone, and/or attached to the amine end-groups ofthe polyol telechelics.

High 1,2-vinyl content can be at least about 40%,such as 50%, 60%, 70%, 80%, 90%, or even greater. Low 1,2-vinyl contentcan be less than about 35%, such as 30%, 20%, 15%, 12%, 10%, 5%, or evenless. The vinyl polyolefin backbone can have various combinations ofcis-, trans-, and vinyl structures, such as having a trans-structurecontent greater than cis-structure content and/or 1,2-vinyl structurecontent, having a cis-structure content greater than trans-structurecontent and/or 1,2-vinyl structure content, or having a 1,2-vinylstructure content greater than cis-structure content or trans-structurecontent.

Other ethylenically and/or acetylenically unsaturated moieties that maybe incorporated onto the backbone of the polyol telechelics includeallyl groups and α,β-ethylenically unsaturated C₃ to C₈ carboxylategroups. Non-limiting examples of such ethylenically unsaturated moietiesinclude acrylate, methacrylate, fumarate, β-carboxyethyl acrylate,itaconate, and other unsaturated carboxylates disclosed herein. Theseunsaturated moieties can be attached to the hydroxyl groups on thepolyol telechelics by forming ester linkages. The incorporation of theseunsaturated moieties may take place before the formation of prepolymer,or after the prepolymer is reacted with stoichiometrically excessiveamounts of polyamine and/or polyol curatives.

Ethylenically and/or acetylenically unsaturated polyol polyhydrocarbonscan be liquid at ambient temperature, such as those having vinylpolybutadiene homopolymers or copolymers as backbones, and can have lowto moderate viscosity, low volatility and emission, high boiling point(such as greater than 300° C.), and molecular weight of about 1,000 toabout 5,000, such as about 1,800 to about 4,000, or about 2,000 to about3,500.

Fatty Polyacids

Fatty polyacids can be derived from monounsaturated and/orpolyunsaturated fatty acids through reactions involving the doublebonds, such as ozonolysis (e.g., forming azelaic acid from oleic acid),caustic oxidation (e.g., forming sebacic acid from ricinoleic acid orcastor oil), and polymerization (e.g., dimerization). Polymeric fattyacids can be formed from a polymerization reaction of a saturated,ethylenically unsaturated, or acetylenically unsaturated fatty acid andat least one compound to provide a second acid moiety or a functionalgroup convertible to the second acid moiety. Polymeric fatty acids mayresult from the polymerization of oils or free acids or esters thereof,via dienic Diels-Alder reaction to provide a mixture of dibasic andhigher polymeric fatty acids. In place of these methods ofpolymerization any other method of polymerization may be employed,whether the resultant polymer possesses residual unsaturation or not.

Fatty acids can be long-chain monobasic fatty acids having a C₆ orlonger chain, such as C₁₁ or longer or C₁₆ or longer, and C₂₄ orshorter, such as C₂₂ or shorter. Unsaturated fatty acids and estersthereof can be monounsaturated and/or polyunsaturated, monocarboxylicand/or polycarboxylic, and include, without limitation, oleic acid,linoleic acid, linolenic acid, palmitoleic acid, elaidic acid, erucicacid, hexadecenedioic acid, octadecenedioic acid, vinyl-tetradecenedioicacid, eicosedienedioic acid, dimethyl-eicosedienedioic acid,8-vinyl-10-octadecenedioic acid, methyl, ethyl, and other esters (suchas linear or branched alkyl esters) thereof, and mixtures thereof. Alsodimerizable are fatty acid mixtures obtained in the hydrolysis ofnatural fats and/or oils, such as olive oil fatty acids, sunflower oilfatty acids, soybean fatty acids, corn oil fatty acids, canola fattyacids, cottonseed oil fatty acids, coriander oil fatty acids, tallowfatty acids, coconut fatty acids, rapeseed oil fatty acids, fish oilfatty acids, tall oil fatty acids, methyl, ethyl, and other estersthereof, and mixtures thereof.

The polymeric fatty acids can be adduct acid, such as adduct diacidformed between a conjugated ethylenically unsaturated fatty acid (e.g.,linoleic acid, soybean oil fatty acid, tall oil fatty acid) and ashort-chain unsaturated acid (e.g., acrylic acid, methacrylic acid,crotonic acid). Methods for producing such adduct acids are described,for example, in U.S. Pat. Nos. 5,136,055, 5,053,534, 4,156,095, and3,753,968. Alternatively, the polymeric fatty acid can be obtained byhydroformylating an unsaturated fatty acid and then oxidizing it intofatty dicarboxylic acid. For example, oleic acid can be reacted withcarbon monoxide and hydrogen to form 9(10)-formyloctadecanoic acid,which can then be oxidized to 9(10)-carboxyoctadecanoic acid.

Polymeric fatty acids may also be obtained in known manners (e.g.,addition polymerization using heat and a catalyst) from one monobasicfatty acid or a blend of two or more monobasic fatty acids, themonobasic fatty acids being saturated, ethylenically unsaturated, oracetylenically unsaturated. The resulting polymeric fatty acids areoften referred to in the art as dimers (i.e., dimerized fatty acids),trimers (i.e., trimerized fatty acids) and so forth (e.g., oligomericfatty acids). Saturated monobasic fatty acids can be polymerized atelevated temperatures with a peroxidic catalyst such as di-t-butylperoxide. Suitable saturated monobasic fatty acids include linear orbranched acids such as caprylic acid, pelargonic acid, capric acid,lauric acid, myristic acid, palmitic acid, isopalmitic acid, stearicacid, arachidic acid, behenic acid, and lignoceric acid.

Ethylenically unsaturated monobasic fatty acids and esters thereof canbe polymerized via non-catalytic polymerization at a higher temperature,or using catalysts such as acid or alkaline clays, di-t-butyl peroxide,boron, trifluoride and other Lewis acids, anthraquinone, sulfur dioxideand the like. Methods of dimerizing unsaturated fatty acids and theiresters are described in U.S. Pat. No. 6,187,903, among others. Suitablemonomers include linear or branched acids having at least oneethylenically unsaturated bond, such as about 2-5 of such bonds, like3-octenoic acid, 11-dodecanoic acid, linderic acid, oleic acid, linoleicacid, linolenic acid, hiragonic acid, eleostearic acid, punicic acid,catalpic acid, licanoic acid, clupadonic acid, clupanodonic acid,lauroleic acid, myristoleic acid, tsuzuic acid, palmitoleic acid,gadoleic acid, cetoleic acid, nervonic acid, moroctic acid, timnodonicacid, arachidonic acid (i.e., eicosatetraenoic acid), nisinic acid,scoliodonic acid, and chaulmoogric acid.

Acetylenically unsaturated monobasic fatty acids can be polymerized bysimply heating the acid. The polymerization of these highly reactivematerials can occur in the absence of a catalyst. Any acetylenicallyunsaturated fatty acid, linear or branched, mono-unsaturated orpoly-unsaturated, are useful monomers for the preparation of polymericfatty acids. Suitable examples of such materials include 10-undecynoicacid, tariric acid, stearolic acid, behenolic acid and isamic acid.

Polymerization reaction of the monobasic fatty acids as described above,include so-called dimeric fatty acids, are commonly structural isomermixtures containing a predominant proportion (about 45-95% by weight orgreater) of aliphatic and alicyclic dimer diacids (such as C₃₆ or C₄₄diacids), a small quantity (about 1-35% by weight) of trimer acids andhigher polymeric fatty acids (such as C₅₄₊ polyacids), and some (up toabout 20% by weight) residual monomers (such as C₁₈ or C₂₂ branchedchain monoacids). The ratio between the reactants in the disclosedprocess is known in the art as a topological ratio. Commercial productsof these polymeric fatty acids can contain about 75-95% by weight ofdimeric acids, about 4-22% by weight of trimeric acids, about 1-3% byweight of monomeric acid. The molar ratio of dimeric to trimeric acidcan be about 5:1 to about 36:1. The relative ratios of monomer, dimer,trimer and higher polymer in un-fractionated dimer acid can be dependenton the nature of the starting materials and the conditions ofpolymerization and subsequent distillation.

Dimerized fatty acids may be “crude”, i.e., obtained directly fromdimerization without distillation, or refined to increase dimerconcentration. Refined dimerized acids such as partially or fullyhydrogenated dimer fatty acids can have a dimer content of about 95% byweight or greater, such as at least about 97%, a monomer content ofabout 1%, a trimer content of about 3%, an acid value of about 193-201,a saponification value of about 198, and an iodine value of about 95.Hydrogenated dimer fatty acids can reduce aesthetically unpleasingcolor. The degree of hydrogenation can correspond to an iodine value ofabout 110 or less, such as about 95 or less, according to ASTM D1959-97or D5768-02. The fatty polyacids, such as the dimer diacids and diestersthereof, can be substantially free of interesters, the presence of whichmay hinder subsequent polymerization reactions. Methods for reducinginterester content in fatty polyacids include hydrolysis/extraction asdisclosed in U.S. Pat. No. 6,187,903, which is incorporated herein byreference. The fatty polyacids or esters thereof can have an interestercontent of about 0.2% by weight or less, such as about 0.05% or less.

Dimer diacids may be unsaturated, partly hydrogenated, or completelyhydrogenated (i.e., fully saturated). Non-limiting dimer diacids canhave one of the following structures:

where R is the same or different moieties chosen from hydrogen, alkyl,aryl, aralkyl, alicyclic, cycloalkyl, and alkoxy groups; x+y and m+n areboth at least about 8, such as at least about 10, such as 12, 14, 15,16, 18, 19, or greater.

Fatty polyacids can have at least one divalent hydrocarbon radicalhaving at least 30 carbon atoms, such as 36-180 carbon atoms, which canbe linear, branched, cyclic, and/or substituted, such asmonocycloaliphatic moiety having a 6-membered carbon ring (e.g.,cyclohexene ring), bicycloaliphatic moiety having a 10-membered carbonring, and substituted aliphatic moiety (e.g., halogenated aliphaticmoiety such as fluoroaliphatic polyacids). Fatty polyacids such as dimerdiacids can have an acid value of 150-250, such as 170-200 or 190-200, asaponification value of 170-210, and a viscosity at 25° C. of 50,000 cStor less, such as 30,000 cSt or less, 10,000 cSt or less, 500 cSt orgreater, like 600 cSt, 7,500 cSt, 8,500 cSt, 9,000 cSt, and anyviscosity therebetween. Examples are available from HumKo Chemical ofMemphis, Tenn. Fatty polyacids can be branched, such as with linear orbranched alkyl groups. Fluid fatty polyacids can be used as reactivediluents in solvent-borne polyurethane/polyurea compositions to achievehigher solid content.

Polymeric fatty acids and other polyacids as described above, as well asmethods to produce such polyacids can be found in U.S. Pat. Nos.6,670,429, 6,310,174, 6,187,903, 5,545,692, 5,326,815, 4,937,320,4,582,895, 4,536,339, and 4,508,652, among others. To form reactivepolymers of the present disclosure, polymeric fatty acids or estersthereof can also be epoxidized, for example by reaction with peraceticacid, performic acid or with hydrogen peroxide and formic acid or aceticacid. Suitable epoxidized fatty acids and esters are described inBritish Patent Nos. 810,348 and 811,797.

One or more or all of the reactable isocyanate groups within thepolyisocyanate compound can be sterically hindered, so that thepolyisocyanate compound provide the combination of reduced reactivitytoward active hydrogen groups such as primary and secondary amines, andimproved chemical stability toward actinic radiations such as UV light.Sterically hindered NCO group can have the following structure:

where C₁, C₂, and C₃ are independent tertiary (i.e., methine) orquaternary carbon atoms. One, two, or all three of C₁, C₂, and C₃ can befree of C—H bonds. C₁, C₂, and C₃ may in part form a substituted ringstructure having about 4-30 carbon atoms. The ring structure may besaturated, unsaturated, aromatic, monocyclic, polycyclic (e.g.,bicyclic, tricyclic, etc.), or heterocyclic having one or more O, N, orS atoms. The ring structure may have one, two, three, or more moietiesof the structure (8), while the polyisocyanate compound may have one,two, or more of such ring structures. For example, the polyisocyanatemay have a structure of:

where Z₁ to Z₈ are independently chosen from halogenated orunhalogenated hydrocarbon moieties having about 1-20 carbon atoms,halogenated or unhalogenated organic moieties having at least one O, N,S, or Si atom and zero to about 12 carbon atoms, and halogens; Y₁ to Y₄are independently chosen from hydrogen, halogenated or unhalogenatedhydrocarbon moieties having about 1-20 carbon atoms, halogenated orunhalogenated organic moieties having at least one O, N, S, or Si atomand zero to about 12 carbon atoms, and halogens; Z is halogenated orunhalogenated hydrocarbon moieties having about 1-60 carbon atoms, orhalogenated or unhalogenated organic moieties having at least one O, N,S, or Si atom and zero to about 60 carbon atoms.

Elastomer compositionscomprising DDI as described in U.S. Publication No. 2003/0135008 areincorporated herein by reference.

The polyisocyanate can have NCO groups of different reactivity, i.e.,being regioselective. Reactants having high regioselectivity in generalcan enable efficient use in consecutive reactions such as polymerizationsteps and crosslinking. They can provide cost advantages by reducingwaste of functional groups (i.e., reduction in unreacted reactants),provide handling advantages by reducing volatile “leftover” molecules,and provide performance advantages by enabling controlled architecturein the reaction products (e.g., reduced polydispersity). Regioselectivepolyisocyanates can be asymmetric in structure, having at least twosterically different NCO groups, one being more sterically interferedthan the other. The more sterically interfered NCO group can be directlyattached to a tertiary carbon atom, or be one methine carbon atom awayfrom either a quaternary carbon atom or two tertiary carbon atoms. Theless sterically interfered NCO group can be at least two carbon atomsaway from either a quaternary carbon atom or two tertiary carbon atoms,and can be attached directly to a methylene carbon or a methine carbon.Regioselective polyisocyanates can have a structure of:

where R₁, R₂, and R₄ are independent organic moieties having about 1-20carbon atoms, such as linear or branched aliphatic hydrocarbon moietieshaving about 1-12 carbon atoms, like C₁ to C₈ alkyl groups; R₃ isorganic moieties having about 2-20 carbon atoms, such as linear orbranched aliphatic hydrocarbon moieties having about 2-12 carbon atoms,like C₂ to C₁₀ alkylene moiety; R₅ and R₆ are the same or differentorganic moieties having about 1-20 carbon atoms, such as linear orbranched aliphatic hydrocarbon moieties having about 1-8 carbon atoms,like C₁ to C₄ alkylene moieties; R₇ is organic moieties having zero toabout 20 carbon atoms, such as hydrogen or linear or branched aliphatichydrocarbon moieties having about 1-12 carbon atoms, like C₁ to C₈ alkylgroups; R₈ is organic moieties having about 1-20 carbon atoms, such aslinear or branched aliphatic hydrocarbon moieties having about 1-12carbon atoms, like C₁ to C₈ alkylene moiety; and x, y, and z areindependently 0 or 1. The regioselective polyisocyanates can besaturated aliphatic or alicyclic.

In certain polyisocyanates, the NCO groups initially have about the samereactivity, but the reaction of a first NCO group with an activehydrogen functionality can induce a decrease in the reactivity of asecond NCO group. Non-limiting examples of such polyisocyanates includepolyisocyanates whose NCO groups are coupled via a delocalized electronsystem, such as tolidine diisocyanate, tolylene 2,4-diisocyanate(2,4-TDI), tolylene 2,6-diisocyanate (2,6-TDI),diphenylmethane-2,4′-diisocyanate (2,4′-MDI), phenylene-1,3- and1,4-diisocyanate, naphthylene-1,5-diisocyanate, triisocyanatotoluene,and biphenyl diisocyanate.

Polyisocyanates can be derived from the fatty polyacids of the presentdisclosure. The fatty polyisocyanates can have the same hydrocarbonstructures as the fatty polyacids, except that each COOH group isreplaced by an NCO group. For example, dimer diacids can be used to formsaturated and/or unsaturated dimer diisocyanates. Dimer diisocyanatesmay be linear, branched (such as with linear or branched alkyl groups),cyclic, and/or substituted, and can be unsaturated, partly hydrogenated,or completely hydrogenated (i.e., fully saturated). Non-limiting dimerdiisocyanates can have one of the following structures:

where R is the same or different moieties chosen from hydrogen, alkyl,aryl, aralkyl, alicyclic, cycloalkyl, and alkoxy groups; x+y and m+n areboth at least about 8, such as at least about 10, such as 12, 14, 15,16, 18, 19, or greater.

Fatty polyisocyanates can have at least one divalent hydrocarbon radicalhaving at least 30 carbon atoms, such as 36-180 carbon atoms, which canbe linear, branched, cyclic, and/or substituted, such asmonocycloaliphatic moiety having a 6-membered carbon ring (e.g.,cyclohexene ring), bicycloaliphatic moiety having a 10-membered carbonring, and substituted aliphatic moiety (e.g., halogenated aliphaticmoiety such as fluoroaliphatic polyisocyanates). Fatty polyisocyanatessuch as dimer diisocyanates are water insensitive, have controllablereactivity and low toxicity when compared to other aliphaticpolyisocyanates. The fatty polyisocyanates can have a % NCO content of20% or less, 15% or less, 10% or less, 5% or greater, or any amountstherebetween, such as 6-9%, 12-16%, 13-15%, or 13.6-14.3%. The fattypolyisocyanates can have a molecular weight of 250 or greater, such as500 or greater or 600 or greater, and up to about 15,000, such as about500-10,000. Fatty polyisocyanates can be liquid at room temperature,having low to moderate viscosity at 25° C. (e.g., about 100-10,000 cP orabout 500-5,000 cP). Other dimer diisocyanates are described in, forexample, Kirk-Othmer Encyclopedia of Chemical Technology 1979, volume 7,3^(rd) edition, p. 768-782, John Wiley and Sons, Inc., the disclosure ofwhich is entirely incorporated herein by reference.

Any and all of the compounds having two or more isocyanate-reactivefunctionalities as disclosed herein may be used as curatives to cureprepolymers into thermoplastic or thermoset compositions. Thesecuratives can be polyamines, polyols, aminoalcohols, polyaminetelechelics, and polyol telechelics, and aminoalcohol telechelics. Tofurther improve the shear resistance of the resulting elastomers,trifunctional curatives, tetrafunctional curatives, and higherfunctionality curatives can be used to increase crosslink density. Othercuratives include those disclosed in U.S. Pat. No. 4,808,691, fromcolumn 9, line 24 to column 12, line 16, in U.S. Pat.

No. 10/339,603,which is incorporated by reference herein in its entirety. For example,the curative may be modified with a freezing point depressing agent tocreate a curative blend having a slow onset of solidification andstorage-stable pigment dispersion. A number of curatives have relativelyhigh freezing points, e.g., hexamethylene diamine (105.8° F.),diethanolamine (82.4° F.), triethanolamine (69.8° F.),diisopropanolamine (73.4° F.), and triisopropanolamine (111.2° F.).

The freezing point depressing agent can be added in an amount sufficientto reduce the freezing point of the curative blend by a suitable amountto prevent loss of pigment dispersion, but not adversely affect thephysical properties of the resulting golf ball, such as about 5% byweight or greater of the total blend, about 8%, about 10%, about 12%,about 14%, or any amount therebetween or even greater. After freezingand subsequent thawing, the modified curative blend can have a pigmentdispersion of greater than 0 on the Hegman scale, such as about 1, about2, about 3, about 4, about 5, about 6, about 7, or some leveltherebetween or even greater.

Mixtures of various alcohols canbe used, such that n stands for an integer or a statistical average ofgreater than about 2 to about 10, preferably about 2 to about 4, andmore preferably about 3. Per mole of the polyols mentioned, (n−0.6) to(n−2.2), (n−0.8) to (n−1.2), or (n−1) moles of (meth)acrylic acids canbe used. These compounds or product mixtures include the reactionproducts of:

(ii) (meth)acrylic acid in the stated molar ratio. Said compounds have amolecular weight of 116 to 1000, such as 116 to 750 or 116 to 158.

Furthermore, the reaction products of said monols comprising(meth)acryloyl groups with, for example, ε-caprolactone can also beused. Such products can be obtained, for example, as Tone® M-100, M-101,and M-201 monomers from Dow Chemical. These compounds have a molecularweight of 230 to 3000, such as 230 to 1206 or 344 to 572.

(Meth)acryloyl alcohols also include urethane (meth)acrylates thatcontain (meth)acryloyl groups and free hydroxyl groups, such as reactionproducts of urethane (meth)acrylates with diols, optionally mixed withpolyols. Aliphatic, cycloaliphatic and/or aromatic diols can be used asdiols, for example ethylene glycol, the isomeric propanediols,butanediols, pentanediols, hexanediols, heptanediols, octanediols,nonanediols and cyclohexanedimethanol, hydrogenated bisphenol-A andderivatives of the above mentioned diols substituted with one or moreC₁-C₆-alkyl groups.

Polyurea Compositions

The compositions of the disclosure may comprise at least one polyureaformed from the well-known one-shot method or prepolymer method. In thelatter, polyamine telechelic is reacted with excess polyisocyanate toform polyurea prepolymer, which is then reacted with curative to formthe polyurea. Prepolymer to curative ratio can be as high as 1:0.9 or1:0.95, such as when primary polyamine curatives are used, or as low as1:1.1 or 1:1.05, such as 1:1.02, such as when secondary polyaminecuratives are used. Curative includes polyamines, polyols, polyacids,aminoalcohols, aminoacids, and hydroxy acids, especially those disclosedherein, as well as epoxy-functional reactants, thio-containingreactants, and any other isocyanate-reactive compounds and materials.The polyurea composition can be castable, thermoplastic, thermoset, ormillable.

The content of reactable isocyanate moieties in the polyurea prepolymer,expressed as % NCO by weight, can be manipulated to control such factorsas curing rate, hardness of the resulting material, and the like. Allelse being the same, the hardness of the resulting material can increaseas the % NCO of the prepolymer increases, and can be greater inpolyamine cured compositions than in polyol cured compositions. Thepolyurea prepolymer can be low-melting (such as being fluid at about125° C.) or fluid at ambient temperature. The % NCO by weight in theprepolymer can be less than about 30%, such as about 15%, about 11%,about 9%, about 7%, or even less, or at least about 2%, such as about 3%or about 4% or greater, or any percentage therebetween, such as about5-11%, about 6-9.5%, about 3-9%, about 2.5-7.5%, or about 4-6.8%.

In forming the polyurea prepolymer, polyamine telechelics as disclosedherein can be used alone or in combination of two or more thereof toreact with excess isocyanate. Prepolymers with higher % NCO (e.g., 14%)can be converted to prepolymers with lower % NCO (e.g., 10%) by furtherreacting with one or more other polyamines, polyols, polyaminetelechelics, and/or polyol telechelics (e.g., polyamine polyamides,polyol polysiloxanes). The polyamine telechelic can have one amidelinkage, two amide linkages, one or more segments having multiple amidelinkages, or a polyamide backbone. When a plurality of amide linkages ispresent, one or more of them can conjoin consecutive repeating units oralternating repeating units. Polyurea prepolymers may contain a contentof free isocyanate monomers by about 10% and up to about 20% of thetotal weight, which can be stripped down to about 1% or less, such asabout 0.5% or less.

When forming a saturated prepolymer, such as for use in highlylight-stable compositions, saturated polyisocyanates being aliphatic,alicyclic, and/or heteroaliphatic can be used alone or in combinationsof two or more thereof. Araliphatic polyisocyanates, alone or inmixtures of two or more thereof, may also be used to form relativelylight-stable materials. Without being bound to any particular theory, itis believed that the direct attachment of the NCO moieties to aliphaticside chains without conjugation with the aromatic rings prevents thearaliphatic polyisocyanates from, or diminishes their ability in,forming extended conjugated double bonds, which may give rise todiscoloration (e.g., yellowing). The sterically hindered polyisocyanatesare useful in forming highly or relatively light-stable materials.Without being bound to any particular theory, it is believed that thesteric hinderance around the N atom tends to rotate it out of plane,thereby reducing its absorbance of UV wavelengths and achieving desiredlight-stability. Moreover, one or more of the NCO groups in thesterically hindered polyisocyanates can be attached to tertiary orquaternary carbon atoms that are substantially free of C—H bonds, thuseliminating or reducing the occurrence of UV-induced oxidation at thecarbon atoms, and in turn slowing degradation or discoloration. Thesaturated polyisocyanates, the araliphatic polyisocyanates, and thesterically hindered polyisocyanates may be used alone or in anycombinations of two or more thereof.

One or more of the polyoltelechelic, the polyisocyanate, and the curative can be chosen fromthose disclosed herein, can be saturated, and the resulting polyurethanecan be saturated. Polyurethane prepolymers can have free isocyanatemonomers by about 10% and up to about 20% of the total weight, which canbe stripped down to about 1% or less, such as about 0.5% or less.

The polyurethane composition can be castable, thermoplastic, thermoset,or millable. The % NCO by weight in the prepolymer can be less thanabout 30%, such as about 15%, about 11%, about 9%, about 7%, or evenless, or at least about 2%, such as about 3% or about 4% or greater, orany percentage therebetween, such as about 5-11%, about 6-9.5%, about3-9%, about 2.5-7.5%, or about 4-6.8%. In forming the polyurethaneprepolymer, polyol telechelics as disclosed herein can be used alone orin combination of two or more thereof to react with excess isocyanate.Prepolymers with higher % NCO (e.g., 14%) can be converted toprepolymers with lower % NCO (e.g., 10%) by further reacting with one ormore other polyamines, polyols, polyamine telechelics, and/or polyoltelechelics (e.g., polyamine polyamides, polyol polysiloxanes). Thepolyol telechelic can have one or two amide linkages, one or moresegments having multiple amide linkages, or a polyamide backbone. When aplurality of amide linkages is present, one or more of them can conjoinconsecutive repeating units or alternating repeating units.

Crosslinkable polyurethanes can be formed from polyol telechelics,curatives, and stoichiometrically deficient amounts of polyisocyanatesuch as diisocyanate. Any one or more the reactants can have one or morealiphatic, non-benzenoid >C══C< moieties for crosslinking. Suchpolyurethanes can have rubber elasticity and wear resistance andstrength, and can be millable. Polyol telechelics of lowcrystallizability, such as those having linear or branched side chainsand those formed by random copolymerization (e.g, polyol polyethers,polyol polyesters, polyol polyetheresters, and others as disclosedherein), can be used to form such polyurethanes. Non-limiting examplesinclude polyethylene propylene adipate polyols, polyethylene butyleneadipate polyols, polytetramethylene ether glycols (such as those havingM_(w) of about 2,000), tetrahydrofuran (THF)-alkyl glycidyl ether randomcopolymers, and other polyol polyesters based on adipic acid and diolslike ethanediol, butanediol, methylpropanediol, hexanediol. Polyoltelechelics can be incorporated with ethylenic and/or acetylenicunsaturation moieties as disclosed above, such as by reacting them withα,β-ethylenically unsaturated carboxylic acids, and then crosslinkedusing vulcanizing agents as disclose herein. Alternatively, thepolyurethanes are substantially free of ethylenic

After a period of time (e.g., 2.5minutes) the molds are cooled (e.g., 10 minutes with tap water or 1minute with tap water and then 4 minutes with chilled water) and themolded objects are released from the molds.

Properties of crosslinkable polyurethanes include Mooney viscosity at100° C. of 40-70 (e.g., 50, 60, 65, or therebetween), tensile strengthof 2,000-6,000 psi (e.g., 3,000 psi, 4,000 psi, 5,000 psi, ortherebetween), tear strength of 300-600 lb/in (e.g., 400 lb/in, 500,lb/in, or therebetween), brittle point of −70° F. or lower (e.g., −80°F., −90° F., or lower), material hardness of 25 Shore A to 60 Shore D(e.g., 55 Shore D), elongation at break of 100-700% (e.g., 300%, 400%,500%, 600%, or therebetween), Bashore rebound of 40-70% (45%, 55%, ortherebetween), and abrasion index (ASTM D-1630) of 300 or greater.

The compositions of the disclosure may comprise at least onepoly(urethane-co-urea) formed from poly(urethane-co-urea) prepolymer andcurative. Prepolymer to curative ratio can be as high as 1:0.9 or1:0.95, such as when primary polyamine curatives are used, or as low as1:1.1 or 1:1.05, such as 1:1.02, such as when secondary polyaminecuratives are used. Curative includes polyamines, polyols, polyacids,aminoalcohols, aminoacids, and hydroxy acids, especially those disclosedherein, as well as epoxy-functional reactants, thio-containingreactants, and any other isocyanate-reactive compounds and materials.

Poly(urethane-co-urea) prepolymer refers to isocyanate-functionalprepolymer having at least one urethane linkage and at least one urealinkage in the backbone. Such a prepolymer is distinct from polyurethaneprepolymer, polyurea prepolymer, and blends thereof. Thepoly(urethane-co-urea) prepolymer can be formed by reacting excessisocyanate with a blend of at least one polyamine telechelic and atleast one polyol telechelic. Molar ratio of polyol telechelic topolyamine telechelic in the blend can be about 0.5:1 to about 10:1, suchas about 0.6:1 to about 7:1. Examples of blend include polyether polyolssuch as polyoxytetramethylene diol and polyether polyamines such aspolyoxypropylene diamine.

The poly(urethane-co-urea) composition can be castable, thermoplastic,thermoset, or millable. The % NCO by weight in the prepolymer can beless than about 30%, such as about 15%, about 11%, about 9%, about 7%,or even less, or at least about 2%, such as about 3% or about 4% orgreater, or any percentage therebetween, such as about 5-11%, about6-9.5%, about 3-9%, about 2.5-7.5%, or about 4-6.8%. Prepolymers withhigher % NCO (e.g., 14%) can be converted to prepolymers with lower %NCO (e.g., 10%) by further reacting with one or more other polyamines,polyols, polyamine telechelics, and/or polyol telechelics (e.g.,polyamine polyamides, polyol polysiloxanes).

The poly(urethane-co-urea) prepolymer can be formed by reacting excessisocyanate with an aminoalcohol telechelic (or a blend of two or morethereof), optionally mixed with at least one polyamine reactant and/orat least one polyol reactant.

Polyaminereactants include any one or more polyamine telechelics and polyaminesdisclosed herein. Polyol reactants include any one or more polyoltelechelics and polyols disclosed herein. The poly(urethane-co-urea)prepolymer can further be formed in situ from a mixture of at least onepolyisocyanate, at least one cyclic compound such as cyclic ether, andat least one telechelic chosen from polyamine telechelics, polyoltelechelics, and aminoalcohol telechelics as disclosed herein.

Acid-Functionalized and Ionomerized Compositions

The reactive compositions of the present disclosure can be covalentlyincorporated or functionalized with ionic groups or precursor groupsthereof, which can impart desirable properties to the resulting polymermaterials. The term “ionic group or precursor group thereof” means agroup either already in an anionic or cationic form or else, byneutralization with a reagent, readily converted to the anionic orcationic form respectively. The term “neutralize” as used herein forconverting precursor groups to ionic groups refers not only toneutralization using true acids and bases but also includesquatemarization and ternarization. Illustrative of precursor anionicgroups (and neutralized form) are acid groups like carboxylic group—COOH(—COO^(⊖)), sulfonic group —SO₂OH(—SO₂O^(⊖)), and phosphoric group(i.e., ══POOH or ══POO^(⊖)); illustrative of precursor cationic groups(and neutralized form) are ══N(══N—^(⊕)), ══P(══P—^(⊕)), and══S(══S—^(⊕)).

Without being bound to any particular theory, it is believed that acidfunctional moieties or groups can improve adhesion of the resultingmaterial to other components or layers in the golf ball, while strongelectrostatic interactions among cationic and/or anionic groups formionic aggregates, which may afford desired mechanical and opticalproperties such as cut and abrasion resistance and transparency. Morethan one type of ionic group or precursor group thereof may beincorporated into the reactive composition of the present disclosure.Acid and/or ionic functionalization of the reactive compositions isdisclosed, for example, in U.S. Pat. Nos. 6,610,812, 6,207,784,6,103,822, and 5,661,207.

The precursor groups of ionic groups can be incorporated into theisocyanate-reactive telechelic (including polyamine telechelics, polyoltelechelics, and aminoalcohol telechelics), the isocyanate, and/or thecurative before, during, or after the prepolymer formation or the curingreaction. They can be neutralized to corresponding ionic groups before,during, or after the prepolymer formation or the curing reaction. Forexample, the acid groups may be neutralized to form the correspondingcarboxylate anion, sulfonate anion, and phosphate anion by treatmentwith inorganic or organic bases. Cationic precursor groups such astertiary amine, phosphine, and sulfide groups can be neutralized byneutralization or quaternarization of the tertiary amine, or reactingthe phosphine or sulfide with compounds capable of alkylating thephosphine or sulfide groups.

Suitable inorganic bases used for partial or total neutralization mayinclude ammonia, oxides, hydroxides, carbonates, bicarbonates andacetates. Cation for the inorganic base can be ammonium or metal cationssuch as, without limitation, Group IA, IB, IIA, IIB, IIIA, IIIB, IVA,IVB, VA, VB, VIIA, VIIB, VIIB and VIIIB metal ions, which include,without limitation, lithium, sodium, potassium, magnesium, zinc,calcium, cobalt, nickel, tin, iron, copper, manganese, aluminum,tungsten, zirconium, titanium and hafnium. Suitable organic bases usedfor partial or full neutralization can be hindered organic tertiaryamines such as tributylamine, triethylamine, tripropylamine, triethylenediamine, dimethyl cetylamine and similar compounds. Primary or secondaryamines may be used, such as if the neutralization takes place after thepolymer is formed, because the amine hydrogen can react with theisocyanate groups thereby interfering with the polyurea or polyurethanepolymerization. One of ordinary skill in the art is aware of additionalappropriate chemicals for neutralization.

At least a portion of the ionic groups can be covalently incorporatedinto the isocyanate-reactive telechelic before prepolymer formation.Suitable acid functional isocyanate-reactive telechelics may have anymolecular weight, such as 1,500, an acid number (calculated by dividingacid equivalent weight to 56,100) of at least about 5, such as at leastabout 10, at least about 25, at least about 30, or at least about 50,may be about 420 or less, such as about 200 or less, about 150 or less,about 100 or less, and an acid functionality of greater than 1, such as1.4 or greater. In the case of polyol telechelics, the hydroxyl numberof the polyols may be at least about 10, such as at least about 20, atleast about 50, or at least about 65, may be about 840 or less, such asabout 300 or less, about 200 or less, about 150 or less. The polyoltelechelics may also have a hydroxyl functionality (average number ofhydroxyl groups per polyol molecule) of greater than 1, about 2 orgreater, like 1.8, and up to about 4. The acid functional telechelic canbe liquid or wax at ambient temperature, and can have a viscosity at 60°C. of less than 5,000 cP, or 3,000 cP or less, such as 2,700 cP or less.

Ionic groups or precursor groups thereof may be incorporated into themonomers comprised in the telechelic. Monomers containing one or moreionic groups or precursor groups thereof can be, but are not limited to,cyclic ethers or diol monomers used to form polyether chains orsegments, cyclic esters, diol monomers or polycarboxylic acids (such aslithium neutralized sulfonated isophthalic acid, tricarboxylic acids, orhigher acids) used to form polyester chains or segments, cyclic amides,diamine monomers or polycarboxylic acids used to form polyamide chainsor segments, cyclic siloxanes used to form polysiloxane chains orsegments, (meth)acrylic acids used to form poly(meth)acrylic chains orsegments, and fatty polyacids having three or more carboxylic acidfunctionalities and isocyanate-reactive derivatives thereof.Alternatively, the ionic groups or precursor groups thereof may beincorporated into the telechelic via the likes of addition orcondensation reactions between suitable functional groups. For example,unsaturated carboxylic acids such as (meth)acrylic acids and unsaturatedfatty acids as disclosed herein may react with unsaturation in thetelechelic, thereby forming pendant carboxylic acids along thetelechelic chain.

Other methods of incorporating acid groups into the telechelic reactantare disclosed, for example, in U.S. Patent Application No. 2002/0183443,which is incorporated by reference herein in its entirety. For example,dimethylolpropionic acid (DMPA) can provide acid groups by reacting witha starting polyol and a diisocyanate to form an isocyanate-terminatedprepolymer at a temperature that permits the reaction of the hydroxylgroups with excess isocyanate without consuming all of the acid groups.Mono- or polycarboxylic acids or mono- or polyanhydrides (such as thosedisclosed herein, like hexanedioic acid) can provide acid groups byreacting with the starting polyols in the absence of an isocyanate,under reaction conditions that permit the reaction of the anhydride withthe hydroxyl groups of the polyol, but are mild enough to preventfurther reaction of the residual carboxylic acids with hydroxyl groups.Examples of such isocyanate-free acid functional polyol telechelicsinclude Lexorez® 1405-65 and 4505-52, both available from InolexChemical Company of, Philadelphia, Pa. (These acid functional polyoltelechelic and other polyols as disclosed herein can further react withmono- or polycarboxylic acids or mono- or polyanhydrides (such as thosedisclosed herein, like aromatic anhydrides such as trimelliticanhydride, pyromellitic dianhydride, and phthalic anhydride, oralicyclic anhydrides such as hexahydrophthalic anhydride and(2,5-dioxotetrahydrol)-3-methyl 3-cyclohexene-1,2 dicarboxylicanhydride) to form additional acid functional polyol telechelics.

At least a portion of the ionic groups can be covalently incorporatedinto the isocyanate before prepolymer formation. Isocyanates having atleast one acid functional group may be formed by reacting a isocyanateand an acid functional group containing compound as described in U.S.Pat. Nos. 4,956,438 and 5,071,578, the disclosures of which areincorporated herein by reference.

The acid groups may also be incorporated during a post-polymerizationreaction, wherein the acid functional groups are introduced or attachedto the polyurea, the polyurethane, or the poly(urethane-co-urea).Moreover, the acid functional polyurea, polyurethane, orpoly(urethane-co-urea) made by ways of copolymerization as describedabove may be further incorporated with additional acid functional groupsthrough such post-polymerization reactions. Suitable agents toincorporate acid functional groups and methods for making are describedat least in U.S. Pat. No. 6,207,784, the disclosure of which isincorporated by reference herein. One of ordinary skill in the art wouldbe aware of other ways to prepare the acid functional polymercomposition. For example, a combination of the means for acidfunctionality incorporation as described above may be used as describedin U.S. Pat. No. 5,661,207, the disclosure of which is incorporated byreference herein.

For example, wetting additives may beadded to the modified curative blends of the disclosure to moreeffectively disperse pigments. Suitable wetting agents are availablefrom Byk-Chemle and Crompton Corporation, among others.

a) Catalysts

One or more catalysts may be employed to alter the reaction rate betweenthe prepolymer and the curative for the reactive compositions. Inpolyurethane compositions, positive catalysts (i.e., promoters) aretypically used to speed up the reaction between isocyanate groups andhydroxyl groups. In polyurea compositions, negative catalysts (i.e.,inhibitors) may be used to slow down the typically fast reaction betweenisocyanate groups and amine groups. The same catalyst may be a promoterin a polyurethane system and an inhibitor in a polyurea system. Suitablecatalysts include, but are not limited to, bismuth catalysts; zinccatalysts such as zinc octoate; cobalt catalysts such as cobalt (II)octoate; zirconium catalysts such as zirconium (IV) acetoacetonate andzirconium (IV) acetylacetone-2,4-pentanedione; tin catalysts such asdibutyltin dilaurate (DABCO® T-12), dibutyltin diacetate (DABCO® T-1),dibutyltin maleate, dioctyltin dilaurate, dibutyltin di-2-ethylhexoate,tin(II) ethylhexoate, tin(II) laurate, tin(II) octoate, dibutyltinoxide, tin (II) chloride, tin (IV) chloride, dibutyltin dimethoxide(FASCAT®-4211), dibutyltin dibutoxide (FASCAT® 4214), dioctyltindiisooctylmercaptoacetate (FORMEZ® UL-29), dibutyltindiisooctylmercaptoacetate, dimethyltin diisooctylmercaptoacetate,dibutyltin dilaurylmercaptide, dioctyltin dilaurylmercaptide,dimethyltin dilaurylmercaptide, stannous octoate (DABCO® T-9), butylstannoic acid, dimethyl-bis[1-oxonedecyl)oxy] stannane (FORMEZ® UL-28),and 1,3-diacetoxytetrabutylstannoxane; titanium catalysts such as2-ethylhexyl titanate, tetraisopropyl titanate, tetrabutyl titanate, andtetrakis-2-ethylhexyl titanate; amine catalysts such astriethylenediamine (DABCO® 33-LV), triethylamine, tributylamine, andN-methylmorpholine; organic acids such as acetic acid, adipic acid,azelaic acid, and oleic acid; delayed catalysts such as phenol-blocked1,8-diaza-bicyclo(5,4,0)undecene-7 (Polycat™ SA-1/10), Polycat™ SA-1,Polycat™ SA-2, Polycat™ SA-102, Polycat™ 8154, Polycat™, and the like.These catalysts can be used alone or in combinations of two or morethereof.

Delayed action catalysts can also be used. These catalysts display theircatalytic activity at a later time point in the reaction. They can beheat-activated, when external heating and/or internal heat from theexothermal reaction elevate the temperature of the reaction mixture toor above the activation temperature of the catalyst. One group of thedelayed action catalyst is cyclic amidines, which can have a genericstructure of:

where n=0 or 1; R₁ to R₇ are independently chosen from hydrogen andlinear or branched aliphatic, alicyclic, araliphatic, and aromaticmoieties, such as C₁-C₄ linear or branched alkyl, C₅-C₁₀ cycloalkyl,C₇-C₁₃ aralkyl, and C₆-C₁₈ aryl moieties, or at least one of R₂/R₃,R₄/R₅, R₆/R₇, R₂/R₄ and R₂/R₆ is a C₁-C₅ alkylene moiety; R₈ is chosenfrom hydrogen and linear or branched aliphatic, alicyclic, araliphatic,and aromatic moieties having 1-36 carbon atoms, optionally substitutedby one or more of OH, COOH, OR, NR₉R₁₀, or comprising at least one (upto about 10) of keto, amide, and ester moieties, or—CH(R)—[OCH₂—CH(R)]_(p)—H, where p is 1-40, R is chosen from linear orbranched C₁-C₂₀ alkyl, cycloalkyl, aryl, and aralkyl moieties (e.g.,C₁-C₁₅ alkyl, C₆-C₁₉ aryl), R₉ and R₁₀ are independently chosen fromhydrogen and linear or branched aliphatic, alicyclic, araliphatic, andaromatic moieties (e.g., C₁-C₁₂ linear or branched alkyl, C₆-C₈cycloalkyl) or R₉/R₁₀ is a C₄-C₆ alkylene moiety. Alternatively, thesecyclic amidines can be used as blocking agent to block isocyanatefunctionalities in the prepolymer, allowing the isocyanate-blockedprepolymer to be thoroughly blended with the curative, and thende-blocking the prepolymer to enable the cure. This mechanism can beused in curing of polyurea composition to slow down reaction and extendpotlife. These and other cyclic amidines as disclosed in U.S. Pat. No.4,698,426 are incorporated herein by reference.

The catalyst can be added in an amount sufficient to catalyze thereaction of the components in the reactive mixture, such as about0.001-5% by weight of the composition, about 0.005-1%, about 0.05% orgreater, or about 0.5% or greater. Use of low levels of tin catalysts,such as about 0-0.04%, may require high temperatures to achieve asuitable reaction rate, which can result in degradation of theprepolymer. Greater amounts of catalysts may allow reduction in processtemperatures with comparable cure, and allow reduction in mixing speeds.Unconventionally high amounts of catalysts can be about 0.01-0.55%,about 0.05-0.4%, or about 0.1-0.25%.

Diluents

As used herein, the term “diluent” refers to any compound or compositionthat can reduce viscosity, reduce reaction exotherm, and/or impart orenhance properties such as flame retardancy, processability,compatibility, and moisture resistance, without adversely affecting thequalitative or physical properties of the resulting polymer. Diluentsare distinct from solvents in that diluents remain within the polymerpost-cure, while solvents are evaporated off post-cure. Diluent can belinear or branched, aliphatic, alicyclic, aromatic, or araliphatic,saturated or unsaturated, substituted or unsubstituted, halogenated orhalogen-free, and/or hydrophobic or hydrophilic, and include within itsscope plasticizer materials. Diluents can be reactive or substantiallyunreactive. Diluent can be substantially water insoluble. Diluent can beadded at any time before, during, or after prepolymer preparation, e.g.,separately or as a mixture with one or more reaction components prior toprepolymer preparation, in amount sufficient to reduce the viscosity ofthe prepolymer to about 1,000-4,000 cP at temperatures of about 125° C.or less. Diluents can have a viscosity of about 50 cP or less at 25° C.Diluents can have a boiling point of greater than 90° C.

The diluent can be used individually or in blends of two or morethereof, and can comprise at least about 0.05% by weight of theprepolymer or the total reactive composition, such as 2%, 3%, 4%, 5%,6%, 10%, 15%, 18%, 20%, 35%, 50%, 60%, 70%, or greater or any amounttherebetween. Suitable diluent can be chosen according to parameterssuch as compatibility with the composition and desired properties of thefinal polymer. For example, ester diluents tend to be compatible withpolyester-based prepolymers. Reactive diluents can react with one ormore functionalities of one or more ingredients in the composition. Forexample, epoxy and carbonate diluents can react with ingredients havingamine groups and/or hydroxyl groups, while ethylenically unsaturateddiluents can react with ingredients having ethylenic unsaturation.

Suitable diluents include those described in U.S. Pat. Nos. 3,773,697,5,929,153, 3,929,700 and 3,936,410, and 4,343,925 (column 9, line 37 tocolumn 13, line 62), the disclosures of which are incorporated herein byreference.

Core Compositions

The cores of the golf balls formed according to the disclosure may besolid, semi-solid, hollow, fluid-filled, gas-filled, powder-filled,one-piece or multi-component cores. The term “semi-solid” as used hereinrefers to a paste, a gel, or the like. Any core material known to one ofordinary skill in that art is suitable for use in the golf balls of thedisclosure. Suitable core materials include thermoset materials, such asrubber, styrene butadiene, polybutadiene, isoprene, polyisoprene,trans-isoprene, as well as thermoplastics such as ionomer resins,polyamides, and polyesters, and thermoplastic or thermoset polyurethaneor polyurea elastomers.

For example, an inner core center or a corelayer may comprise at least one of the reactive compositions disclosedherein.

The golf ball core can comprise one or more materials chosen from baserubber (natural, synthetic, or a combination thereof, such aspolybutadiene), crosslinking initiator (such as dialkyl peroxide),co-crosslinking agent (such as those having di- or polyunsaturation andat least one readily extractable hydrogen in the α position to theunsaturated bonds), filler, cis-to-trans catalyst, organosulfurcompound, among others. Choices for these materials are known to oneskilled in the art, such as those disclosed in co-pending andco-assigned U.S. Patent Publication No. 2003/0119989, bearing Ser. No.10/190,705, the disclosure of which is incorporated by reference herein.The core compositions can be used to form any other portions of the golfball, such as one or more of the intermediate layers and cover layers.

Intermediate Layer Compositions

When the golf ball comprises at least one intermediate layer, such asone disposed between the cover and the core, or an inner cover layer orouter core layer, i.e., any layer(s) disposed between the inner core andthe outer cover of the golf ball, this layer can be formed from any oneor more thermoplastic and thermosetting materials known to those ofordinary skill. These materials can be any and all of the compositionsdisclosed herein, including those listed under “Composition Blends”above, as well as those disclosed in U.S. Patent Publication No.2003/0119989 and U.S. Pat. Nos. 5,334,673 and 5,484,870, which are allincorporated by reference herein.

The intermediate layer may include homopolymers or copolymers ofethylene, propylene, butylene, butene, and/or hexene, optionallyincorporating functional monomers such as acrylic and methacrylic acid,optionally being fully or partially neutralized ionomer resins and theirblends, imidized, amino group containing polymers, polycarbonate,reinforced polyamides, polyphenylene oxide, high impact polystyrene,polyether ketone, polysulfone, poly(phenylene sulfide),acrylonitrile-butadiene, acrylic-styrene-acrylonitrile, poly(ethyleneterephthalate), poly(butylene terephthalate), poly(ethylene vinylalcohol), poly(tetrafluoroethylene) and their copolymers includingfunctional comonomers, and blends thereof. The intermediate layer mayinclude at least one ionomer, such as acid-containing ethylene copolymerionomers, including E/X/Y terpolymers where E is ethylene, X is anacrylate or methacrylate-based softening comonomer in 0-50 wt. %, and Yis acrylic or methacrylic acid in 5-35 wt. % (such as 8-35 wt. % or 8-20wt. %).

The acid copolymers can be E/X or E/X/Y copolymers where E is ethylene,X is α,β-ethylenically unsaturated carboxylic acid or a combination oftwo or more thereof, such as having about 3-8 carbon atoms (e.g.,acrylic acid and/or methacrylic acid), and Y is a softening co-monomer,such as alkyl (meth)acrylate where the alkyl group can be linear orbranched and have about 1-8 carbon atoms (e.g., n-butyl). By“softening,” it is meant that the crystallinity is disrupted (thepolymer is made less crystalline). X can be at least about 2 wt. % ofthe copolymer, such as 2-30, 3-30, 4-20, 4-25, 5-20, or 5-20 wt. % ofthe polymer, and Y can be present in 0-30, 3-25, 10-23, 17-40, 20-40, or24-35 wt. % of the acid copolymer.

Soft, resilient ionomers included in this disclosure can be partiallyneutralized ethylene/(meth) acrylic acid/butyl (meth)acrylate copolymershaving a melt index (MI) and level of neutralization that results in amelt-processible polymer that has useful physical properties. Thecopolymers are at least partially neutralized. At least 40%, or at least55%, such as about 70% or about 80% of the acid moiety of the acidcopolymer can be neutralized by one or more alkali metal, transitionmetal, or alkaline earth metal cations, such as lithium, sodium,potassium, magnesium, calcium, barium, or zinc, or a combination of suchcations.

Soft, resilient, thermoplastic, “modified” ionomers are also exemplarymaterials for use in any one or more golf ball portions present in anyconstruction, such as the inner center, inner core layer, intermediatecore layer, outer core layer, intermediate layer, inner cover layer,intermediate cover layer, outer cover layer, and the like andequivalents thereof. The “modified” ionomer can comprise a melt blend of(a) the acid copolymers or the melt processible ionomers made therefromas described above and (b) one or more organic acid(s) or salt(s)thereof, wherein greater than 80%, or greater than 90%, even 100% of allthe acid of (a) and of (b) can be neutralized by one or more cations.Amount of cations in excess of the amount required to neutralize 100% ofthe acid in (a) and (b) can be used to neutralize the acid in (a) and(b). Blends with fatty acids or fatty acid salts can be used.

The organic acids or salts thereof can be added in an amount sufficientto enhance the resilience of the copolymer, and/or substantiallyeliminate crystallinity of the copolymer. The amount can be at leastabout 5% by weight of the total amount of copolymer and organic acid(s),such as at least about 15%, or at least about 20%, and up to about 50%,such as up to about 40% or up to about 35%. Alternatively, the amount ofthe organic acids or salts thereof can be about 25-150 phr by weight ofthe copolymer or blend of copolymers. The non-volatile, non-migratoryorganic acids can be aliphatic, mono-functional, saturated orunsaturated organic acids or salts thereof as described below, such asthose having less than about 36 carbon atoms, like fatty acids (e.g.,stearic acid and oleic acid) or salts thereof. Agents other than organicacids/salts may be used, as long as they also exhibit ionic arrayplasticizing and ethylene crystallinity suppression properties.

Processes for fatty acid/salt modifications are known in the art. Themodified highly-neutralized soft, resilient acid copolymer ionomers canbe produced by:

-   -   (a) melt-blending 1) ethylene, α,β-ethylenically unsaturated C₃        to C₈ carboxylic acid copolymer(s) or melt-processible        ionomer(s) thereof, optionally having crystallinity disrupted by        addition of a softening monomer or other means, with 2)        sufficient amount of non-volatile, non-migratory organic acids        to substantially enhance the resilience and to disrupt or remove        the remaining ethylene crystallinity, and then, concurrently or        subsequently; and    -   (b) adding a sufficient amount of a cation source to increase        the level of neutralization of all the acid moieties (including        those in the acid copolymer and in the organic acid if the        non-volatile, non-migratory organic acid is an organic acid) to        the desired level.

The ethylene-acid copolymers with high levels of acid (X) are difficultto prepare in continuous polymerizers because of monomer-polymer phaseseparation. This difficulty can be avoided however by use of “co-solventtechnology” as described in U.S. Pat. No. 5,028,674, or by employingsomewhat higher pressures than those which copolymers with lower acidcan be prepared. The weight ratio of X to Y in the composition can be atleast about 1:20, such as at least about 1:15, or at least about 1:10,and up to about 2:1, such as up to about 1.2:1, up to about 1:1.67, upto about 1:2, or up to about 1:2.2.

The acid copolymers can be “direct” acid copolymers (containing highlevels of softening monomers). As noted above, the copolymers can bepartially, highly, or fully neutralized, such as at least about 40%,45%, 50%, 55%, 70, 80%, 90%, or 100% neutralized. The MI of the acidcopolymer should be sufficiently high so that the resulting neutralizedresin has a measurable MI in accord with ASTM D-1238, condition E, at190° C., using a 2160 gram weight, such as at least about 0.1 g/10 min,at least about 0.5 g/10 min, or about 1 g/10 min or greater. In highlyneutralized acid copolymer, the MI of the acid copolymer base resin canbe at least about 20 g/10 min, at least 40 g/10 min, at least 75 g/10min, at least 100 g/10 min, or at least 150 g/10 min.

Specific acid-copolymers include ethylene/(meth)acrylic acid/n-butyl(meth)acrylate, ethylene/(meth) acrylic acid/iso-butyl (meth)acrylate,ethylene/(meth) acrylic acid/methyl (meth) acrylate, and ethylene/(meth)acrylic acid/ethyl (meth)acrylate terpolymers. The organic acids andsalts thereof employed can be aliphatic, mono-functional (saturated,mono-unsaturated, or poly-unsaturated) organic acids, including thosehaving fewer than 36 carbon atoms, such as 6-26, 6-18, or 6-12 carbonatoms. The salts may be any of a wide variety, including the barium,lithium, sodium, zinc, bismuth, potassium, strontium, magnesium andcalcium salts of the organic acids. Non-limiting examples of the organicacids include caproic acid, caprylic acid, capric acid, lauric acid,stearic acid, behenic acid, erucic acid, oleic acid, and linoleic acid.Other fatty acids and salts thereof include any and all of thosedisclosed herein above, such as fatty polyacids and polymerized fattypolyacids (e.g., dimer diacids) and salts thereof. Partial esters ofpolyacids (i.e., having at least one un-esterified acid group) and saltsthereof are also useful. When mono- and/or poly-unsaturated organicacids and/or salts thereof are used, the ionomer composition can becrosslinked into a thermoset material using reactants known to oneskilled in the art, such as peroxide and/or sulfur initiators, some ofwhich are disclosed herein. Alternatively, radiations such as electronbeam radiation and others disclosed herein can be used to crosslink theionomer composition. Optional additives include acid copolymer wax(e.g., Allied wax AC 143 believed to be an ethylene/16-18% acrylic acidcopolymer with a number average molecular weight of 2,040), which assistin preventing reaction between the filler materials (e.g., ZnO) and theacid moiety in the ethylene copolymer, TiO₂ (a whitening agent), opticalbrighteners, etc.

Ionomers may be blended with conventional ionomeric copolymers andterpolymers, and non-ionomeric thermoplastic resins. The non-ionomericthermoplastic resins include, without limit, thermoplastic elastomerssuch as polyurethane, poly-ether-ester, poly-amide-ether,polyether-urea, PEBAX (a family of block copolymers based onpolyether-block-amide, commercially supplied by Atochem),styrene-butadiene-styrene (SBS) block copolymers,styrene(ethylene-butylene)-styrene block copolymers, etc., poly amide(oligomeric and polymeric), polyesters, polyolefins including PE, PP,E/P copolymers, etc., ethylene copolymers with various comonomers, suchas vinyl acetate, (meth)acrylates, (meth)acrylic acid,epoxy-functionalized monomer, CO, etc., functionalized polymers withmaleic anhydride grafting, epoxidization etc., elastomers such as EPDM,metallocene catalyzed PE and copolymer, ground up powders of thethermoset elastomers, etc. Such thermoplastic blends can comprise about1% to about 99% by weight of a first thermoplastic and about 99% toabout 1% by weight of a second thermoplastic.

Examples of these materials aredisclosed in U.S. Pat. Nos. 6,565,466 and 6,565,455, which areincorporated herein by reference. In addition, polyamides, discussed inmore detail below, may also be blended with ionomers.

The intermediate layer composition may include 1-99 phr (such as 5-90phr, 10-75 phr, or 10-50 phr) of at least one grafted metallocenecatalyzed polymer and 99-1 phr (such as 95-10 phr, 90-25 phr, or 90-50phr) of at least one ionomer.

One example ofa polyamide/non-ionomer blend is a polyamide and non-ionic polymersproduced using non-metallocene single-site catalysts. As used herein,the term “non-metallocene catalyst” or “non-metallocene single-sitecatalyst” refers to a single-site catalyst other than a metallocenecatalyst. Examples of suitable single-site catalyzed polymers aredisclosed in U.S. Pat. No. 6,476,130, of which the disclosure isincorporated by reference herein. The intermediate layer may also beformed from the compositions as disclosed in U.S. Pat. No. 5,688,191,the disclosure of which is incorporated by reference herein.

As with the core, the intermediate layer may alsoinclude a plurality of layers. It will be appreciated that any number ortype of intermediate layers may be used, as desired.

The intermediate layer may also be a tensioned elastomeric materialwound around a solid, semi-solid, hollow, fluid-filled, or powder-filledcenter. As used herein, the term “fluid” refers to a liquid or gas andthe term “semi-solid” refers to a paste, gel, or the like. A wound layermay be described as a core layer or an intermediate layer for thepurposes of the disclosure. The would layer may be formed from acomposition of the disclosure having at least one hydrophobic backboneor segment for improved water resistance.

No. 6,149,535, or a high tensile filament as disclosed inco-pending U.S. Patent Publication No. 2002/0160859, or coated with abinding material to improve adhere to the core and cover, as disclosedin U.S. Patent Publication No. 2002/0160862. The disclosures of theabove-mentioned patents and publications are incorporated by referenceherein.

While hardness gradients can be used in a golf ball to achieve certaincharacteristics, the present disclosure also contemplates thecompositions of the disclosure being used in a golf ball with multiplecover layers having essentially the same hardness, wherein at least oneof the layers can be modified in some way to alter a property thataffects the performance of the ball. Such ball constructions aredisclosed in co-pending U.S. Application Publication No. 2003/0232666and incorporated by reference herein. Other non-limiting golf ballconstructions include those described in U.S. Pat. Nos. 6,548,618,6,149,535, 6,056,842, 5,981,658, 5,981,654, 5,965,669, 5,919,100,5,885,172, 5,803,831, 5,713,801, 5,688,191, as well as in U.S.Application Publication Nos. 2002/0025862 and 2001/0009310, thedisclosures of which are incorporated by reference herein.

Methods of Forming Layers

The golf balls of the disclosure may be formed using a variety ofapplication techniques such as compression molding, flip molding,injection molding, retractable pin injection molding, reaction injectionmolding (RIM), liquid injection molding (LIM), casting, vacuum forming,powder coating, flow coating, spin coating, dipping, spraying, and thelike. Conventionally, compression molding and injection molding areapplied to thermoplastic materials, whereas RIM, liquid injectionmolding, and casting are employed on thermoset materials. These andother manufacture methods are disclosed in U.S. Pat. Nos. 6,207,784 and5,484,870, the disclosures of which are incorporated herein byreference.

The compositions of the disclosure may be formed over the core using acombination of casting and compression molding. For example, U.S. Pat.No. 5,733,428, the disclosure of which is hereby incorporated byreference, discloses a suitable method for forming a polyurethane coveron a golf ball core. Because this method relates to the use of bothcasting thermosetting and thermoplastic material as the golf ball cover,wherein the cover is formed around the core by mixing and introducingthe material in mold halves, other reactive liquid compositions such aspolyurea compositions may also be used employing the same castingprocess. Once the polyurea composition is mixed, an exothermic reactioncommences and continues until the material is solidified around thecore. Viscosity can be measured over time, so that the subsequent stepsof filling each mold half, introducing the core into one half andclosing the mold can be timed in order to center the core and achieveoverall uniformity. A suitable viscosity range for molding the reactivecomposition can be about 2,000-30,000 cP, such as about 8,000-15,000 cP.

For illustration, the prepolymer and curative can be mixed in amotorized mixer inside a mixing head by metering amounts of the curativeand prepolymer through the feed lines. Top preheated mold halves can befilled and placed in fixture units using centering pins moving intoapertures in each mold half. At a later time, the cavity of a bottommold half, or the cavities of a series of bottom mold halves, can befilled with similar mixture amounts as used in the top mold halves.After the reacting materials have resided in top mold halves for about40-100 seconds, such as about 50-90 seconds, about 60-80 seconds, orabout 70-80 seconds, golf ball subassemblies such as cores can belowered at a controlled speed into the reacting mixture. Ball cups canhold the subassemblies by applying reduced pressure (or partial vacuum).Upon location of the subassemblies in the top mold halves after gellingfor about 4-12 seconds, such as about 5-10 seconds, the vacuum can bereleased to release the subassembly. The top mold halves can then beremoved from the centering fixture unit, inverted and mated with thebottom mold halves having a selected quantity of reacting compositiongelling therein. Other non-limiting molding techniques include thosedisclosed in U.S. Pat. Nos. 5,006,297 and 5,334,673, and others known tothose skilled in the art, which are incorporated herein by reference.

Injection molding and/or compression molding may be used. For example,half-shells of thermoplastic compositions may be made by injectionmolding or compression molding in conventional half-shell molds, thenplaced about the pre-formed subassembly within a compression moldingmachine, and compression molded at about 250-400° F. The molded ballscan then be cooled in the mold and removed when the molded layer is hardenough to be handled without deforming. Prior to forming the layer, thesubassembly may be surface treated to increase the adhesion between thesubassembly and the molded layer. Examples of surface treatmenttechniques can be found in U.S. Pat. No. 6,315,915, which areincorporated by reference.

Dimples

The use of various dimple patterns and profiles provides a relativelyeffective way to modify the aerodynamic characteristics of a golf ball.As such, the manner in which the dimples are arranged on the surface ofthe ball can be by any available method. Non-limiting dimple patternsinclude icosahedral (U.S. Pat. No. 4,560,168), octahedral (U.S. Pat. No.4,960,281), phyllotactic (U.S. Pat. No. 6,338,684), and Archimedean(U.S. Pat. No. 6,705,959) with non-linear parting line, includingtruncated octahedron, great rhombcuboctahedron, truncated dodecahedron,and great rhombicosidodecahedron. The dimples can be circular and/ornon-circular, such as amorphous (U.S. Pat. No. 6,409,615), have tubularlattice pattern (U.S. Pat. No. 6,290,615), having catenary curvature(U.S. Patent Publication No. 2003/0114255), have varying sizes (U.S.Pat. Nos. 6,358,161 and 6,213,898), and/or have high percentage ofsurface coverage (U.S. Pat. Nos. 5,562,552, 5,575,477, 5,957,787,5,249,804, and 4,925,193). These disclosures are all incorporated byreference herein.

Golf Ball Post-Processing

The golf balls of the present disclosure may be painted, coated, orsurface treated for further advantages. The use of light stable reactivecompositions may obviate the need for certain post-processing such asapplying pigmented coating or clear topcoat, thus reducing cost andproduction time, reducing use of volatile organic compounds (VOCs), andimproving labor efficiency. Toning the golf ball cover with titaniumdioxide can enhance its whiteness. The cover can be subjected to suchsurface treatment as corona treatment, plasma treatment, UV treatment,flame treatment, electron beam treatment, and/or applying one or morelayers of clear paint, which optionally may contain one or morefluorescent whitening agents. Trademarks and/or other indicia may bestamped, i.e., pad-printed, on the cover, and then covered with one ormore clear coats for protection and glossy look. UV treatment can beused to cure UV-curable topcoat and/or ink layer (used as a paint layeror a discrete marking tool for logo and indicia), as disclosed in, forexample, U.S. Pat. Nos. 6,500,495, 6,248,804, and 6,099,415. One or moreportions of the golf ball may be subjected to dye sublimation, asdisclosed in U.S. Patent Publication No. 2003/0106442, and/or lasermarking or ablation, as disclosed in U.S. Pat. Nos. 5,248,878 and6,462,303. The disclosures of these patents and publications areincorporated by reference herein.

Golf Ball Properties

Physical properties of each golf ball portion, such as hardness,modulus, compression, and thickness/diameter, can affect playcharacteristics such as spin, initial velocity, and feel. It should beunderstood that the ranges herein are meant to be intermixed with oneanother, i.e., the low end of one range may be combined with the highend of another range.

Component Dimensions

Golf balls and portions thereof of the present disclosure can have anydimensions, i.e., thickness and/or diameter. While USGA specificationslimit the size of a competition golf ball to 1.68 inches or greater indiameter, golf balls of any sizes smaller or larger can be used forleisure play. As such, the golf ball diameter can be 1.68-1.8 inches,1.68-1.76 inches, 1.68-1.74 inches, or 1.7-1.95 inches. Golf ballsubassemblies comprising the core and one or more intermediate layerscan have a diameter of 80-98% of that of the finished ball. The core mayhave a diameter of 0.09-1.65 inches, such as 1.2-1.63 inches, 1.3-1.6inches, 1.4-1.6 inches, 1.5-1.6 inches, or 1.55-1.65 inches.Alternatively, the core diameter can be 1.54 inches or greater, such as1.55 inches or greater, or 1.59 inches or greater, and 1.64 inches orless. The core diameter can be 90-98% of the ball diameter, such as94-96%. When the core comprises an inner center and at least one outercore layer, the inner center can have a diameter of 0.9 inches orgreater, such as 0.09-1.2 inches or 0.095-1.1 inches, and the outer corelayer can have a thickness of 0.13 inches or greater, such as 0.1-0.8inches, or 0.2 or less, such as 0.12-0.01 inches or 0.1-0.03 inches.Two, three, four, or more of outer core layers of different thicknesssuch as the ranges above may be used in combination.

Thickness of the intermediate layer may vary widely, because it can beany one of a number of different layers, e.g., outer core layer, innercover layer, wound layer, and/or moisture/vapor barrier layer. Thethickness of the intermediate layer can be 0.3 inches or less, such as0.1 inches, 0.09 inches, 0.06 inches, 0.05 inches, or less, and can be0.002 inches or greater, such as 0.01 inches or greater. Theintermediate layer thickness can be 0.01-0.045 inches, 0.02-0.04 inches,0.025-0.035 inches, 0.03-0.035 inches. Two, three, four, or more ofintermediate layers of different thickness such as the ranges above maybe used in combination. The core and intermediate layer(s) together forman inner ball, which can have a diameter of 1.48 inches or greater, suchas 1.5 inches, 1.52 inches, or greater, or 1.7 inches or less, such as1.66 inches or less.

The cover thickness can be 0.35 inches or less, such as 0.12 inches, 0.1inches, 0.07 inches, or 0.05 inches or less, and 0.01 inches or greater,such as 0.02 inches or greater. The cover thickness can be 0.02-0.05inches, 0.02-0.045 inches, or 0.025-0.04 inches, such as about 0.03inches. Thickness ratio of the intermediate layer (e.g., as an innercover layer) to the cover (e.g., as an outer cover layer) can be 10 orless, such as 3 or less, or 1 or less.

Hardness

Golf balls can comprise layers of different hardness, e.g., hardnessgradients, to achieve desired performance characteristics. The hardnessof any two adjacent or adjoined layers can be the same or different. Oneof ordinary skill in the art understands that there is a differencebetween “material hardness” and “hardness, as measured directly on agolf ball.” Material hardness is defined by the procedure set forth inASTM-D2240 and generally involves measuring the hardness of a flat“slab” or “button” formed of the material in question. Hardness, whenmeasured directly on a golf ball (or other spherical surface) isinfluenced by a number of factors including, but not limited to, ballconstruction (i.e., core type, number of core and/or cover layers,etc.), ball (or sphere) diameter, and the material composition ofadjacent layers, and can therefore be different from the materialhardness. The two hardness measurements are not linearly related and,therefore, cannot easily be correlated.

The cores of the present disclosure may have varying hardness dependingat least in part on the golf ball construction. The core hardness asmeasured on a formed sphere can be at least 15 Shore A, such as at least30 Shore A, about 50 Shore A to about 90 Shore D, about 80 Shore D orless, about 30-65 Shore D, or about 35-60 Shore D. The intermediatelayer(s) of the present disclosure may also vary in hardness, dependingat least in part on the ball construction. The hardness of theintermediate layer can be about 30 Shore D or greater, such as about 50Shore D or greater, about 55 Shore D or greater, or about 65 Shore D orgreater, and can be about 90 Shore D or less, such as about 80 Shore Dor less or about 70 Shore D or less, or about 55-65 Shore D. Theintermediate layer can be harder than the core layer, having a ratio ofhardness of about 2 or less, such as about 1.8 or less, or about 1.3 orless. The intermediate layer can be different (i.e., harder or softer)than the core layer with a hardness difference of at least 1 unit inShore A, C, or D, such as at least 3 units, or at least 5 units, or atleast 8 units, or at least 10 units, or less than 20 units, or less than10 units, or less than 5 units.

The hardness of the cover layer may vary, depending at least in part onthe construction and desired characteristics of the golf ball. On theShore C scale, the cover layer may have a hardness of about 70 Shore Cor greater, such as about 80 Shore C or greater, and about 95 Shore C orless, such as about 90 Shore C or less.

The difference or ratio of hardness between the cover layer and theinner ball can be manipulated to influence the aerodynamics and/or spincharacteristics of a ball. When the intermediate layer (such as innercover layer) is at least harder than the cover layer (such as outercover layer), or intended to be the hardest portion in the ball, e.g.,about 50-75 Shore D, the cover layer may have a material hardness ofabout 20 Shore D or greater, such as about 25 Shore D or greater, orabout 30 Shore D or greater, or the cover hardness as measured on theball can be about 30 Shore D or greater, such as about 30-70 Shore D,about 40-65 Shore D, about 40-55 Shore D, less than about 45 Shore D,less than about 40 Shore D, about 25-40 Shore D, or about 30-40 Shore D.The material hardness ratio of softer layer to harder layer can be about0.8 or less, such as about 0.75, about 0.7, about 0.5, about 0.45, orless. When the intermediate layer and the cover layer have substantiallythe same hardness, the material hardness ratio can be about 0.9 orgreater, and up to 1.0, and the cover layer may have a hardness of about55-65 Shore D. Alternatively, the cover layer can be harder than theintermediate layer, with the hardness ratio of the cover layer to theintermediate layer being about 1.33 or less, such as about 1.14 or less.

The core may be softer than the cover. For example, the cover hardnessmay be about 50-80 Shore D, and the core hardness may be about 30-50Shore D, with the hardness ratio being about 1.75 or less, such as about1.55 or less or about 1.25 or less.

Compression

As used herein, the terms “Atti compression” or “compression” refers tothe deflection of an object or material relative to the deflection of acalibrated spring, as measured with an Atti Compression Gauge availablefrom Atti Engineering Corp. of Union City, N.J. Compression values ofthe golf ball or portion thereof can be at least in part dependent onthe diameter. Atti compression of the core or portion thereof can be 80or less, such as 75 or less, 40-80, 50-70, 50 or less, 25 or less, 20 orless, 10 or less, or 0, or below the measurable limit of the AttiCompression Gauge. The core or portion thereof may have a Soft CenterDeflection Index (SCDI) compression of 160 or less, such as 40-160 or60-120. The golf ball can have an Atti compression of 40 or greater,such as 55 or greater, 50-120, 60-120, 50-120, 60-100, 75-95, or 80-95.

Initial Velocity and COR

USGA limits the initial velocity of a golf ball up to 250±5 ft/s. Theinitial velocity of the golf ball of the present disclosure can be245-255 ft/s, or greater, such as 250 ft/s or greater, 253-254 ft/s, orabout 255 ft/s. Coefficient of restitution (COR) of a ball or a portionthereof is measured by taking the ratio of the outbound or reboundvelocity to the inbound or incoming velocity (such as, but not limitedto, 125 ft/s). COR can be maximized so that the initial velocity iscontained with a certain limit. COR of the golf ball can be 0.7 orgreater at an inbound velocity of 125 ft/s, such as 0.75 or greater,0.78 or greater, 0.8 or greater, and up to about 0.85, such as0.8-0.815. The core and/or the inner ball can have a COR of 0.78 ormore, such as 0.79 or greater.

Spin Rate

Spin rate of a golf ball can at least in part be dependent onconstruction, and can vary off different golf clubs (e.g., driver,woods, irons, wedges, etc.). In a multi-layer (e.g., 2-piece, 3-piece,4-piece, wound) ball, the driver spin rate can be 2,700 rpm or greater,such as 2,700-3,300 rpm, 2,800-3,500 rpm, 2,900-3,400 rpm, or less than2,700 rpm. Non-limiting measurements of spin rate are disclosed in U.S.Pat. Nos. 6,500,073, 6,488,591, 6,286,364, and 6,241,622, which areincorporated by reference herein.

Flexural Modulus

As used herein, the term “flexural modulus” or “modulus” refers to theratio of stress to strain within the elastic limit (measured in flexuralmode) of a material, indicates the bending stiffness of the material,and is similar to tensile modulus. Flexural modulus, typically reportedin Pascal (“Pa”) or pounds per square inch (“psi”), is measured inaccordance to ASTM D6272-02.

The intermediate layer (e.g., outer core layer, inner cover layer) canhave any flexural modulus of 500-500,000 psi, such as 1,000-250,000 psior 2,000-200,000 psi. The flexural modulus of the cover layer (e.g.,outer cover layer, inner cover layer, intermediate cover layer) can be2,000 psi or greater, such as 5,000 psi or greater, 10,000-150,000 psi,15,000-120,000 psi, 18,000-110,000 psi, 100,000 psi or less, 80,000 orless, 70,000 psi or less, 10,000-70,000 psi, 12,000-60,000 psi, or14,000-50,000 psi.

The cover layer (e.g., inner cover, intermediate cover, outer coverlayers) can have any flexural modulus, such as the numerical rangesillustrated for intermediate layer above. When the cover layer has ahardness of 50-60 Shore D, the flexural modulus can be 55,000-65,000psi. In multi-layer covers, the cover layers can have substantially thesame hardness but different flexural moduli. The difference in flexuralmodulus between any two cover layers can be 10,000 psi or less, 5,000psi or less, or 500 psi or greater, such as 1,000-2,500 psi. The ratioin flexural modulus of the intermediate layer to the cover layer can be0.003-50, such as 0.006-4.5 or 0.11-4.5.

Specific Gravity

The specific gravity of a cover or intermediate layer can be at least0.7, such as 0.8 or greater, 0.9 or greater, 1 or greater, 1.05 orgreater, or 1.1 or greater. The core may have a specific gravity of 1 orgreater, such as 1.05 or greater. In one example, the intermediate layerhas a specific gravity of 0.9 or greater and the cover has a specificgravity of 0.95 or greater. In another example, the core specificgravity is 1.1 or greater and the cover specific gravity is about 0.95or greater.

Adhesion Strength

The adhesion, or peel, strength of the compositions as presentlydisclosed can be 5 lb_(f)/in or greater, such as 10 lb_(f)/in orgreater, 20 lb_(f)/in or greater, 24 lb_(f)/in or greater, or 26lb_(f)/in or greater, or lb_(f)/in or less, such as 25 lb_(f)/in, 20lb_(f)/in, or less. Adhesion strength of a golf ball layer can beassessed using cross-hatch test (i.e., cutting the material into smallpieces in mutually perpendicular directions, applying a piece ofadhesive cellophane tape over the material, rapidly pulling off thetape, and counting the number of pieces removed) and repeated ballimpact test (i.e., subjecting the finished golf ball to repeated impactand visually examining the coating film for peeling), as disclosed inU.S. Pat. No. 5,316,730, which is incorporated by reference herein.

Water Resistance

Water resistance of a golf ball portion can be reflected by absorption(i.e., weight gain following a period of exposure at a specifictemperature and humidity differential) and transmission (i.e., watervapor transmission rate (WVTR) according to ASTM E96-00, which refers tothe mass of water vapor that diffuses into a material of a giventhickness per unit area per unit time at a specific temperature andhumidity differential). The golf ball or a portion thereof can have aweight gain of 0.15 g or less, such as 0.13 g, 0.09 g, 0.06 g, 0.03 g,or less, and a diameter gain of 0.001 inches or less, over seven weeksat 100% relative humidity and 72° F. The golf ball portion such as theouter or inner cover layer can have a WVTR of 2 g/(m²×day) or less, suchas 0.45-0.95 g/(m²×day), 0.01-0.9 g/(m²×day), or less, at 38° C. and 90%relative humidity.

Shear/Cut Resistance

The shear/cut resistance of a golf ball portion (e.g., inner or outercover layer) may be determined using a shear test having a scale from 1to 6 in damage and appearance. The cover layer can have a number of 3,2, 1, or less on the shear test scale.

Light Stability

Light stability (such as to UV irradiance power of 1.00 W/m²/nm) of thecover layer (e.g., a visible layer such as an outer cover layer or aninner/intermediate cover layer having transparent or translucent outercover layers) may be quantified using difference in yellowness index(ΔYI, according to ASTM D1925) before and after a predetermined period(such as 120 hrs) of exposure. The ΔYI of the cover layer can be 10 orless, such as 6, 4, 2, 1, or less. Difference in yellow-to-blue chromadimension before and after the exposure (Δb*) can also quantify lightstability. The Δb* of the cover layer can be 4 or less, such as 3, 2, 1,or less.
